Try this link and see if it works. The cool thing about this lift is that it's portable. It can be moved anywhere; you just have connecters installed wherever you need a lift. Or you can get a base for use outside.
The lift you posted looks perfect for what you need! I'm calling about the Flexersiser today -- I'll let you know what I find out.
