If I had unlimited funds, I'd likely sew on a Bernina. Until that time, I'll try to win one. I will freely admit to coveting the Bernina walking foot, which I believe to be the best in the biz. The BSR (stitch regulator for free motion quilting) would also be sweet. I have a tendency to go a little large on stitches when FMQ'ing swirly shapes.
This post isn't sponsored, but they do have monthly prizes for top referrers, so I'm sharing for my Canadian readers to get in on the action and maybe score a few notions. Good luck!!
