I have the Grace -- not sure which one - it's metal. Works great, but if I had lottsa $$$ I'd buy one that would electronically go up and down, etc. :) It will do up to a 108" (or close to that) quilt. I use a mid arm sewing machine on it. Considering the hook up --- that machine will STAY on it!!! The other thing I'd like is a long-arm because you can't do big designs on the mid-arm. However, it's better than nothing!
