Definitely try to get to a big quilt show and try out some different machines--sit down, a true long arm, one that uses a DSM on a frame, etc. so you get a feel for the differences. It would also let you try different brands. Then do some internet research, including checking Craigslist, eBay and the other sites mentioned to see what the prices are in your locale. You might be surprised at the price of used machines(hopefully pleasantly!) Also, start checking auction ads, typically they will go cheaper at an auction.
