I have a Craftsman, now is the best time to buy, as they are getting rid of winter stuff to get ready for lawn mowers and such, that is what we did and got a great deal.
Mine looks like this (few yrs older), except mine has tracks instead of wheels (never but one with tracks, more moving parts to break!) Other than a bad Carb. and something needed adjustment on the tracks (covered under warranty---they even came to my house to fix it), I haven't had any problems with it.
We got nailed with snow too, I'm hoping to use up the gas tonight so I can get ready to store it. Hopefully my neighbor doesn't plow me out before I get home!
