Joe,
I'm in the Houston area, as well, but relocating to Raleigh, NC next week.
I've got an AAE lift that I bought about 5 years ago. It has worked well and I haven't had any problems with it. It is their cheapest lift. If you get on their email list they will (constantly) send you sales. They put the lift on sale about every other week.
My only caution is that I only used the lift for light cars. My MG Midget vintage racecar, my MGA, my MINI. The heaviest cars I have had on it were my Jaguar E-Type (about 3k lb) and a C5 Corvette (about 3.5k lb). Although the lift was rated at 7000 lbs, I would not put my 6200 lb Dodge Diesel truck on it. It just isn't that stout looking and the locking mechanism is a welded-block design.
You have to be careful to properly adjust the release mechanism and to pay attention when lowering the lift. It is possible that one corner can hang and the whole thing starts tilting and many bad things can happen if you aren't paying attention.
Other than that, it has served me well. And, no, the lift isn't for sale. The guy that bought the house included it in the contract!
