Good questions!
There are different things people mean when they say a quilting machine. Sometimes that is a general all around machine that you can do all sorts of things on, including quilting. Sometimes it is a machine dedicated to just quilting, like a long arm. When talking to dealers, you have to stress "quilting as in every day/heavy duty usage". For examples there are cheap Brothers that just will not hold up even though they may say stuff about what they can do with quilting, and there are expensive ones that might be great choices for you.
From looking at the Husqvarna, I think the biggest thing you need is more throat space. The Pfaff 630 does have alphabets -- most machines these days do, depends on if the size you want or not. The 8" throat is ok, not huge. With the desire to do FMQ -- I see no integrated walking foot feature, or stitch regulator? Different brand but for Bernina there is the BSR

I understand brand loyalty -- but if I had a budget and space, I might look at the midarm/sit down machines like maybe Babylock and I know several people here have different set-ups. Will be interesting to me to see their comments.
