I'm an admitted Honda zealot, but it's potentially a lot of tiller for the money. I don't know the specs, but you're comparing one machine with a retail price of $800 to another at $2000. How can there be any comparison? Honda's commercial stuff (and I've never owned any) seems to be built a little stronger and a little less "feature rich" than their homeowner stuff, which is, in turn, a big step up from their "big box" stuff. This tiller may be fine. Does it look trashed? Is it dirty, dented, leaking oil, etc.? Or does it look good? Are the air filter and oil clean? Are all the original adjustment knobs and pins still there? Does the engine fire right up, respond readily to the throttle and not smoke? Is the gearshift easy and smooth? Maybe they'd let you rent it for a day and apply the cost of the rental to the purchase.

Good question, Medusa. The coarse sprays end up dripping off of the leaves. Fine sprays adhere better...so you use less. Coarse sprays also produce fine particles. I used a hose end sprayer in New Orleans for very few roses and in retrospect I realize that I wasted huge amounts of chemicals. With a pump sprayer, I could have covered them with a tsp of spray diluted rather than the several ounces the hose end consumed for each application. Generally we try to use the least toxic sprays that work and we do have the serious face masks (that stop both particulate and chemical fumes) that we first bought when stripping paint, cleaning spaces between century old walls in New Orleans. IF we were using the atomizer, we'd be using even less chemicals, but would have to use face masks. With a fine spray, we should use face masks, but sometimes don't. We are on a hill top with predictable breezes. If we had an urban lot, a serious face mask would be a necessity, not one of the white things from Home Depot. As we and our rose garden mature, we've segregated the roses that need spray from those that don't. And the spray areas area are much smaller. And I continue to redesign the garden for more roses that please me and that can make it through the year in fine style with less or no spray.

I have 2 from Rosemania that I have not had any trouble with - so far. One is the small Duromax (Flo Pro) 1.3 gallon sprayer... http://rosemania.com/shopsite_sc/store/html/product490.html sells for $89.95. I like it because it has a shoulder strap and I can zip around and quickly spray all of my roses in about 30 minutes. The other one is the Spotshot 7 gallon sprayer that you already mentioned earlier.... http://rosemania.com/shopsite_sc/store/html/product93.html I have not had any problems with it either. But it IS rather pricey - $400. It is harder for me to maneuver around the garden when it is full - even though it has wheels. I mainly use it to apply the Bayer All-in-One soil drench. It makes applying that so much easier. I use it without the spray nozzle. Here is a link that might be useful: Duromax (Flo Pro) 1.3 Gallon Battery Powered Sprayer

So, update on my suction cup air plant garden. I've started watering with distilled water, and once every two months diluted orchid food. This way the glass stays clear. The window wall has been very successful, I've added several species, all of which have bloomed and grown. I got an excess orchid that was dying and over crowded, it bloomed and I'm getting it back to health to separate the bulbous bases into several containers. This week I replaced the towel (which the orchids had rooted into) with a long piece of clear plastic that directs the water spill over into the tub. Because the plastic is non-absorbant it lets the mist pool and the orchid roots suck it up, growing much faster and being much greener now. I laid some clear plastic packaging, cut into a neat rectangle, down, and used 1.5 inch wide clear packing tape to hold it in place. I didn't upload photos because you can't' ...well, see it in a photo being clear and against privacy glass. The other thing I did was buy craft store jewelry wire, and begin forming it into shapes to hold the plants. Up close it's kind of cool and holds the plants out at different depths. However, the effect is quickly lost when stepping away. I think I'll have to bend the wire such that plants are more than 8 inches away from the window, at the edge of the spray pattern for the wire wrapping to be striking, I'm thinking about putting the orchids, once split, on little cages so the roots can reach pooled water but there won't be a container and bark that would rot. I know it doesn't look super healthy in the photos but it was on the way out when I got it as a reject freebie, they've improved. You can sort of see the plastic in the close up photo with the wire wrapping. It's super fun to move the plants around, kind of like living fridge magnets. With the multple-times-a-day misting there's not really a need for wood to absorb and slowly release moisture to the orchids so I may be able to go totally without media? I've also been turning a soft drink bottle, with the wrapper pulled off, upside down onto the mister reservoir. This allows the mister to run 2-3 week between refills at 30 second 2X a day misting. I've changed the batteries three times since starting, so batteries last about 1.5 months at a time. The unit came with an AC adapter, but I don't want live wires running around a bathroom. I think I'm going to get a battery charger and c batteries to go with from B&H photo so I'm not throwing away batteries once every two months, I think, if I can perfect the setup, I'd have a reservoir hold a little over 1 month of water at a time (about 5 liters) and add a sprinkle of orchid food the day before I refill. Then I'd do refill, battery recharge and any plant moving around or potting I want as a 2 hour a month hobby. If I want to put about $250 into this, I'll switch out the mister with two ultrasonic fogger bars (several ultrasonic fogger discs along a rectangle) in a cut open PVC pipe with a reservoir at the end. It would require an AC adapter that I'd wire along the ceiling ...and I'm not that committed yet. I have made ultrasonic fog curtains before, and they are fantastically pretty. I sort of envision a fog curtain 2 to 3 times a day gliding down over the plants Here's an internet photo to give the idea of the effect, but I would want it on a 2 foot wide scale.
