I was lucky enough to find a Grace Quilting Frame at the St. V's a few weeks ago. Now I too need to get a mid-arm - the 4"

I get from my Singer just doesn't cut it

Let me know how your research is coming. I don't have a clue but have heard alot of good stuff about Janomes (sp?).
I have a Bernina 730E - I'll have to try it to see if I can squeeze out a little more work space.
