I considered this one. I contacted the company to find out when they would have a unit in my state for me to test drive. It's a good price point and if you have limited space, a good option. You move the quilt, like you would with a domestic machine. There is quite a large harp area compared to a regular sewing machine and a large table, but I decided I didn't want to wrestle quilts anymore, both to pin/baste the sandwich and then to quilt, so I got a Tin Lizzie long arm.
Contact the company to see when a rep will be in your State with a unit. Test drive one with YOUR large quilt, not just a small test piece to make sure it's for you!
