Thank you for your detailed response about the 630, CJ, especially the info about the feed dog width.
I know I want a Bernina with the BSR and thought the 440QE would be THE machine for quilters who didn't want an 820. Was curious about what the 630 offered that made it more desirable. Sounds like its the embroidery feature.
Then was looking at the 820 with the big throat...but, we're going to be full-timing in a fifth-wheel beginning this fall and I think an 820 is going to be too big to drag around, set up, take down, store, etc. Guess I'll wait until the new machines debut this month. Unfortunately, with more models to choose from instead of helping me make a decision, they will probably just add to my confusion :).
Thanks again,
Margaret
