I'm happy as heck with mine. For $4500, I think it's a great deal. I can hang with the big boys on the trail, although they will get me in the wide open areas. I've had it up to 70 and some have said they had theirs up to 90. For a first time sled buyer, or someone who doesn't want to shell out a lot of cash, I'd say this big fan is great! I seem to be getting about 10 mpg, but that's on crap trails for the most part. Not sure on good trails and good riding...Plastic skis are also a bonus...
