Whatever you get, you might want to try it out first, if at all possible. Lots of good, workable machines show up in garage sales at very low prices. ($50 or less) However, before you do FMQ on your precious quilt, practice on something else, like maybe a potholder. My guild has a lovely LA. The "experts" try to get everyone to work on a scrap sandwich, just to loosen up and get the feel of it. I have done most of my FMQ on a variety of home machines. Dropping the feed dog is important. I always use a embroidery/darning foot.
