The best advice I can give you is to do your research. I looked at all the different brands and models online. Decided what features were important to me, and then went to a quilt show where I could test drive the machines that were my top 3 choices. I was able to see how easily the heads moved, maintenance, upgradability, etc. I then purchased the machine that was right for me - an APQS Millie. I bought a demonstrator model at a great price and have been happy with my decision thus far.
