Few years back i purchased a js jacks air operated lift at the Milwaukee snow show at the time they were selling for $450 bucks the best lift I've ever owned, a little pricey just checked the web site only saw them that one year at the show great product!!!
No personal experience... But I have heard many say that the Lift-A-Sled is the best. All aluminum, so super light and no rusting. I may be picking one up myself at H. Days (already planning for the fall. LOL). Picking up an EVO for my boy next w/e. Gotta love spring deals!!!
I bought the Paumco lift basically because it was made & welded in the USA and I thought the rollers looked better than the others. It comes with a hand crank which is a little slow but if you are only using it occasionally it is not an issue. Seemed to be well built and heavy duty---think it was rated at 700 lbs. It was shipped to my house and it was all shrink wrapped on a heavy duty pallet and assembled except for the wheels and pads.
