I have a Juki TL2010Q for quilting. However, it's a straight-stitch machine, so if you don't have another machine for any zig zag or stitches other than straight stitching, that might not be a good choice for you.
That being said, the TL2010Q is a great machine for quilting and piecing. The price is reasonable, the stitches are great, and it's great for FMQ. I've had mine for 3 years now, with no problems whatsoever.
I do have a vintage Singer and a Juki HZL-DX7 that I can use as back-ups and for decorative stitches.
If you're going to have one machine only, the HZL-DX7 does just about everything, however the harp size is a little bit smaller than the TL2010Q.
