Thanks for the suggestions! Juki, Janome, and Brother are high on my list of potentials for a new machine. I will keep researching, but I'm starting to think my purchase might have to wait until the kids are back in school and I have time to visit the local shops to try out different machines. No matter what I end up with, I'll be keeping one of my other machines for piecing and general quilting - I might even keep both, and use the smaller one as my portable class/travel machine.
