Since you're the type of person who tends to keep things a long time, you need something durable. Therefore, if your budget allows it, spend a few hundred dollars more and get one of the Honda HRX models or (if you feel comfortable buying online) a Toro Super Reycler 20382. These mowers are built with more durable components than those on most $200-$400 mowers--well worth the extra money for someone who keeps equipment a long time. The Honda HRX and the Toro Super Recycler both performed very well in Consumer Reports' mower tests, so they shouldn't have any problem handling tall grass.

Please save the negative comments re Lawnboy 2 cycles. I used mine for 21 years and never, ever had a problem until a crack in the aluminum housing literally pulled the engine apart, it lost compression, and there were no parts available to fix it. Loved that mower, loved the 2 cycle, the scent of the exhaust (reminded me of being out on my boat), and the reliability. Nothing on the market will pick up clippings and leaves as well as that mower did, nothing. Caruso

I'm glad that you are happy with your purchase. I have a ten year old Honda. My experience: The engine is indestructable. After 10 years, the carb has gotten gummed up and my choke sticks. Not unreasonable. Simple solution was to quit using the choke. It still starts first pull most of the time even without choking it. I will get around to cleaning the carb one of these days. No complaints about the deck. My deck is steel and shows no rust and very little wear. I have the double blade mulch setup and it does a good job mowing. I mulch most of the time and it only leaves cut grass on top of the lawn if I let it get too long before cutting. But...... I have a slight incline in my yard. Slight. I've had to replace the wheels once because they wore smooth and slid on the incline. I'm getting ready to replace them again because the second set it almost smooth. BTW, my lawn is about 1/3 acre, a corner lot in a subdivision. Cables. I have to replace the cable to the self propelled clutch about every other year. There doesn't seem to be anything that is stressing it, it just breaks after a while. I've replaced the safety/blade clutch cable a couple of times as well. The self propelled cable also needs adjusted yearly. The clamp holding it doesn't seem to be as secure as it should be and it slips, causing the self propelled mechanism to be hit or miss. The bagger frame. It fell apart. Three welds just gave up and it fell to pieces. New ones are quite costly and the replacement seems to be constructed exactly the same as the old one. The fabric bag actually lasted longer than the frame! The handle. The paint came off of it after a couple of years where I hold it while mowing. This isn't my first go around with a mower and I've never had this happen with far cheaper models. I had to cover it with electrical tape to keep it from rusting. Also, the plastic bracket on the right holding the two drive levers crumbled after a couple of years. These are all niggling problems to me because I do the repairs myself. I've always managed to figure a way to mow even when it is broken. On the other hand, if I had to take it in for repair every time, I would probably be pretty unahppy. I'm sure I've spent enough to buy a new one and my wife mentions that every time it breaks. I just hate to get rid of it when the engine and deck are working so well. I'll probably consider Toro and Snapper whenever I break down and decide to replace it.
