I have one I'm fixing to put on the market. Mine is on a grace frame with a stitch regulator. I have really enjoyed quilting on it, but I'm getting a 21" longarm delivered on Saturday. This was a great machine to use as a beginner machine on a frame. I've gained much experience, and it was a very reasonable set up to see if I was going to enjoy quilting that way.
The only draw back is the 9" arm -- you have to turn it frequently, but I would never have invested the money you have to for a large machine without trying this first. I've had it 2 years, and am so thankful for the experience I gained using it.
