We got our new garage lift assembled and working this weekend. A friend of ours had one, and he turned us on to the company: www.gregsmithequipment.com
We ordered the Propark 7 model. It works nicely, and wasn't too hard to assemble. It runs on cables operated by a hydraulic cylinder. The ramps lock into place on the uprights, so there is no stress on the cables and hydraulics once you are upright. It also has snap on wheels that can be used to move the whole unit around. Just be careful if your floor has a pitch to it
Best of all, it was under $2k, and we saved another couple hundred by ordering 2 units with a friend of ours. Ask them when you call, they will discount for multiple units.
If anyone wants photos, let me know and I'll post them.
