I have a Juki TL2010Q and Love it for quilting! It is straight stitch only, but has a nice big and high throat area. Also has needle down/up and auto thread cutter. I've quilted several big quilts on it, before I got my longarm.
Here's one on Ebay that is going for $799 incl. shipping. That's a great price.
