Pro machines don't have a flat bed. Their small tubular arms make working on narrow items incredibly easy. There are things you can do on the pro machines that just can't be done on home machines. I went with a 12 needle and never looked back. Take a look at the new Happy Journey - 7 needle and a semi-pro machine. The Happy Voyager is a true pro machine, and you can find them used for a decent price.
