The 630 is a discontinued model so there may be limited support. I have one that I love for sewing and piecing, but the embroidery module has always been a problem in that it doesn't reliably sense which hoop is in place. (Big disappointment that because when it does embroider it's lovely!) I sew quite a bit and Bernina is one of the machines that needs to go to dealer for routine maintenance. Some sewing machine guys won't service Berninas saying that they're not certified to work on them and don't want to void any warranties. After 10 or 20 years, I'm sure any warranty is long gone. The stitch regulator is going to jack the price up considerably and I don't have one with my machine, but I've heard mixed reviews on results using one. Good luck and I hope this helps.
