I recently added a Juki 2010Q to my business. There's a review on my website if you're interested. At $750, it is an outstanding machine for piecing. In fact, I like it for that better than either of my Berninas.

While the throat space isn't huge like a longarm, or even a midarm, it is larger than a standard sewing machine, and its predecessor (TL98Q) is well loved as a machine to be used on a frame.
