I've had one for a few years. I purchased it with a front blower and its main use is for snow removal from our ~1/3' mile dirt driveway.
Mine is a Hydro, the one issue I have is when your on a downhill slope, there is a hesitation between being stopped and reversing. You will drift further downhill before the transmission engages to allow you to reverse.
The only other issue is with the saddle fuel tanks, there is a check valve between them to keep the right side full which is where the fuel pick up is, however the fuel gauge sensor is on the left side and it can sometimes indicate an erroneous reading, keeping it topped off is one solution. Others have removed the check valve and drilled a small hole to help balance the levels on each side but still try to keep the right side full.
All in all I'm happy with my purchase, the above issues are minor and as long as you are aware of them, they can be dealt with.
