I would suggest that before you invest money into a machine(and this was suggested on you last thread) that you go to a dealer and test drive the different machines available to see what they can do. Also, you may want to sign up for a quilting class to learn the basics of quilting and what you can do with your machine.
Many people do all their quilting on home machines, but it's easier and faster(much more expensive) to use a long-arm machine. It all depends on the space you have, the cash you have and your needs.
From your questions, I'd really suggest you visit a dealer.
