Hello all, shopping for a new to me Arctic Cat, have about $5000 to spend. Just curious about some of the different cat models. The 1M, it can be a 600, 800, or 900? How is the 1M 900 different from the KingCat? I'm a bigger guy at 6'7, 250lbs and I'm thinking I want at least a 700, probably 800 or 900. I see M6, M7, and M8 models in the buy sell for around my price range. I assume these all have electronic reverse and the KingCat and 1M do not? Any models to avoid? I want at least 2003 or newer. I'm not too worried about the extra weight of a 900 but I sure do like reverse. I prefer the extra long tracks, at least 151", preferably longer. Thanks.
