if you love the Janome, then go with it. Janome users are a loyal bunch. I'm a Baby Lock girl myself and equally as loyal to that brand so I understand.
When I bought machines from the dealer, I looked at MSRP and dialed it down by at least 30%. Having a machine for sewing with fancy stitches and the works is nice. Having a machine just for quilting is nice. Having both is AWESOME. However, I find that I expect some of the same features on both machines, like a large throat space, great lighting, motor speed control, needle position control, built-in scissors, feed-dog drop option, and the list goes on.
It's exciting getting a new machine and I wish you much luck and fun. Don't pay dealer prices - NEGOTIATE!
