Mine is a BendPak HD9ST, couldn't be happier. Needs air to lift the safeties, but that's a minor inconvenience, I have air in the shop anyway. I specified the 120 vac motor rather than the 220 vac (no extra charge) that comes with it only because I wanted it that way, hasn't seemed to make a notable difference in lifting power or time to lift. I use mine mainly for oil changes, repairs on my cars and winter storage - I should have bought one years ago, it would have saved me the discomfort/aches/pains of spending time on my back on a cold cement floor. I still bang my head from time to time, wife says that explains a lot.
