If you are looking for a mid-arm quilting machine and frame combo take a look at the Bailey
http://www.baileyssewingcenter.com/homequilter.html
This machine is a bit larger, offering a 13" and 15" machine, where Juki and Janome offer a 9" machine. What's not to like about having more space to quilt your design. Check it out.
They have Grace frames in their package deals. The 4th rail looks like a must have to keep the batting off the floor. I think the prices are good and getting a larger machine is a bonus.
