Take a look (do a search) on the Coronet, the HQ equivalent "Simply 16", the Littlefoot frame, and Brother's Dream Quilter and Dream frame. They are all the same concept - a smaller frame for a small longarm.
You will also want to find a dealer where you can try one, and ESPECIALLY understand what's involved in unmounting and remounting the quilt when needed, and that you will still have to baste the quilt layers before mounting on the frame.
They don't take up as much space as a traditional long arm where you don't need to baste the layers first, but a good sit down mid-arm with plenty of table space might be worth considering.
