It sounds like you will be doing mostly quilting with this machine, is that correct? Not general/garment/home dec sewing?
Also, how much experience do you have with sewing quilting?
What is your budget for a machine?
There's tons of option out there and often your best option is to go to a sewing machine store (or several) and try out some machines to see how you like them and how easy they are for you to use.
