Local dealer for Direct-Lift is Derek Weaver in FW:

A number of us in DFW have their economical 4 post lift. It was around $2K, including $400 for delivery and set up. Do pay the $400, these things are heavy and difficult to assemble. You don't have to bolt it down, but it will need to be repositioned with the casters every few months. They tend to scoot a little as you drive on and off.
