I had the quilt frame/machine set up and felt I wasn't using it enough to justify the space it took up and the size of quilts I was making - which I could free motion on my sewing machine. I sold it and don't miss anything EXCEPT the ease of free motion quilting.
My local dealer got the HQ 16 in and I sat down to demo it and totally fell in love, but the price - $5000 - really threw me for a loop. I'm going to check it out at the Sewing Expo in WA in March and see if they are offering any deals. My dealer will match deals if he can so I'm going wait and see.
