I've read all the posts, and I think the most important thing to do is to test drive a machine....Go to all the sewing machine dealers in your area, and check out the machine that they recommend to you, and a few others...just explain to the sales person that you are just trying to find a good fit for you... they will understand.....PLEASE, make sure that you get a machine with a strong enough motor, quilting takes it's toll. Many of the cheapy machines can't handle 1/2 hour of stippling without shutting down...
P.S. I have worked for a dealer for many years, and have helped many newbies find the right machine for their needs. Good Luck, Susie
