I don't know about the rest of the tiller, but I do know something about the GX31. The Honda small engines can run at all position BUT it can't sit on the side or up side down!!!!! VERY IMPORTANT!!!. It has a oil chamber to whip the oil into mist so you can run in all position. But when the engine stop, oil is going to go to the lowest level due to gravity. If the engine sit side way or up side down, oil will sip through the rings and go into the combussion chamber. If you leave it sit long enough, the engine not only hard to start, also it will smoke for a while. But it will clear up. That is the reason the foam filter soak with oil. So do not just tear the engine up until you run more test. You might want to clean the carb. I just did one on my GX31 and is not that hard. But If you can start the engine, I don't think you even need to do that. Just wash the foam filter with soap and water, put oil and put it back. Change the gas filter and check the plug. You check the oil but putting the engine with cylinder upwards, on flat level. Remove the drain plug and make sure the oil just not overflow. Start and let it run for a little while, the smoke should clear up. Then you can continue testing whether it has power. I am not saying the engine has no problem, just say the smoking is normal if the engine sit in wrong position.

I don't see any screws, but it looks like mine will come apart on the top where the "cracks" are. I don't know how to take it apart, but if It stopped working I would probably try harder, I didn't want to break it. I have never had a problem with any of mine.

I fell asleep on the keyboard again. You should be OK with just about anything. I was at the logitech site taking a look at the G3. It looks like its Logitech's answer to the Razer Copperhead. I guess with the G3 you have the option of just plugging it in or downloading the drivers. You do have the option of switching back and forth or between 800 and 1600 DPI before you download the drivers...and I'm not quite sure what that means. I don't know if that means you can choose which of the two DPI's you want or if it means you can switch back and forth between them at your leisure if you don't download the drivers. Amazon is selling it at 47.00...we are getting higher in price. There are only three user reviews ... but it looks comfortable to use, and if it is plug in and go...with the option of downloading Setpoint (what you use to program your mouse ... if you want) nothing could be easier. Its a thought.

Don't you have to have IE to keep up with windows updates? I have the opposite problem. IE works great and fast for me always has and fire fox constantly freezes on webpages and just does not work right, don't get that as I know most people like it but I prefer IE anyway. I am an odd ball though as I use Norton security and it doesn't slow me down like most and I use incredimail and that doesn't slow me down and most every one else complains about those programs. I keep firefox on here though because one time a few years ago suddenly something happend that took out IE for every one and no one could get on the internet with it one night. Forget what exactly happened but it was wide spread all over. I had firefox installed thank goodness and that connected fine but the people with only one computer and no back up browser had to wait until MS fixed what ever the problem was as I think IE was out until the next day, was very strange.
