I just bought this. I don't need a frame as I do QAYG. I simply can't stand dealing with all the fabric at once. I'll probably use the Pfaff for blocks and the Brother for putting strips together. Even with QAYG, the 2170 needs room. I've played with FMQ on the Pfaff, tried the quilting system and while I liked the movement of the base, the opening left something to be desired as you had no idea where you were. I liked the slider better.
I played with a Tin Lizzie sit down and had a far easier time with that setup than the embroidery machine.
I like the idea of the pin feed. It looks like it works like the Pfaff IDT.
What do you need for safety if you are FMQ smaller blocks individually?
The Brother machines seem to be made to sew without a foot pedal. They use the speed control on the machine. Does this do the same? Manual doesn't mention. Local dealer doesn't carry this machine but will service it.
I like QAYG and have no desire to change styles. I don't get as bored, and I don't have to worry about where to piece a kingsize top if I want one. I did one once on a Pfaff 1471. Never again.
