I put a Janome 1600P machine (around $1200) on a Grace SR-2 quilt frame (around $600) and this works for me. I only do baby, throw, twin sized quilts and table runners. The machine has an 11 inch throat. If I ever wanted to do a larger queen or king sized quilt I'd have to split it into two sections, quilt each and then sew these together as in a quilt as you go quilt. Find what you can afford and work with ...then go for it, even if you have to start small.
