msoop, you can find information about the Bailey Home Quilters here:
http://www.baileyssewingcenter.com/test.html
They come in 13", 15", and 17".
The Little Gracie II is made by the Grace Company:

They have several machine quilting frames that are suitable to different budgets and sizes :)
And finally, to look for used Bailey's and frames, I'd recommend checking out the following 3 Yahoo groups:
http://groups.yahoo.com/group/Baileyquiltingmachines/
http://groups.yahoo.com/group/Gracemachineframe/
http://groups.yahoo.com/group/homequiltingsystems/
All 3 groups have a Database, where people can list items they are selling or items they are looking for. I don't see a lot in there right now, but people are always adding stuff. I'm sure there are other places to look, but those groups have worked well for me; they're all fairly active.
