Although I can do a fairly decent meander on my DSM, it is a struggle to quilt a large quilt, so I bought a 20" sit down Bailey(
http://www.baileyssewingcenter.com/), would have preferred a frame but have no room for one. They are a family owned business and although it's not technically a "longarm", 20" is a heck of a lot more room than on my dsm. They have a pretty good reputation and a "reasonable" price and great customer service.
