So you want to be able to adjust it? That's a little harder but not impossible. When I took in my Bernina for servicing I was ooohing and aahing over an automatic/hydraulic adjustable height table.
Here's one option for a quilt frame:

I believe in tools and that we deserve good tools. With my vision issues I believe in doing what I can to keep on quilting for as long as I can. While not anything I could really just go out and buy myself, I don't think it's excessive if it's what you want and what you need -- even if you have to get a frame to fit. There must be other options, maybe even a local person who does hydraulics and stuff.
