I just purchased one about 1 week ago. So far I really like it. I use it for a mix of work and play, although other models that run faster might be more fun, where I am 25mph is enough due to rough terrain.
I used it all weekend moving rock and loads of dirt around the place and it was great. If you are going to carry heavy loads you will want the electric bed lift option, right now I have a strong young son that works but will need to purchase that option later.
