I purchased my sportsman etx, now called the 450HO, January 2015 from my local dealer with a promotion which included a KFI 48" plow and 2500lb winch. I use this machine primarily for plowing snow, hauling firewood, navigating my ten acres of property along with various other chores around my house. I currently have 58hrs and approximately 225 miles on my bike and have had zero issues to date. All work has been performed by the dealer at the recommended intervals. This was my first ever quad I had purchased so I was new to everything in the atv world, and still am, but learning. As for as the positives, the etx is reliable, comfortable to ride, awesome fuel mileage, plenty of power, for me anyways being used more for utility purposes than anything. The winch and plow work great plowing my long hilly drive in the winter. As far as negatives I do have a couple, with the smaller tires than the 570 ground clearance is limited somewhat, hinges that hold the lid for the front storage compartment are less than to be desired, and the other which is more about me being picky more than anything, is the gear selector being just above your right knee. It just seems that if it was on the left side that it would be out of the way of your leg and you would not have to remove your hand from the throttle and then back again, not a big deal but jmo. In summary this is a great quad for the suggested price and will do just about anything that you need it to do. If you are more into mudding and trail riding, or looking for tons of power and speed, maybe the 570 or a larger model would suit you better. For the money this quad is hard to beat for what you get.
