Several years ago I had an inspira frame and a Pfaff Grand Quilter 1200. I purchased it used from my local dealer for $1500 (that price included both the frame and the machine). I think when the inspira frame first came out, the GQ was the machine they sold with it. It would quilt up to a king size quilt. I found it to be really sturdy and I never had any issues with it. I ended up selling it because it was just too large, took up half my living room, that was the only place I could put it. I now do my fmq on a Brother 1500. Sounds like a good deal to me. You just want to be sure you have a machine that will fit properly on it. I would follow PaperPrincess' advice and call Grace and be sure your 1500 will fit on it.
