There are several frames to choose from out there. I do suggest to not do what I did - which was to buy the frame new... figure out that a home sewing machine will not work well at all for anything on the frame ... then figure out .. man! I could have gotten one on Craigslist with the machine at a huge discount! I did end up buying a Voyager used - hated the weight of it and sold it. Then I bought a 15" Bailey after reading the boards and hearing complaints about the machines people bought.
I guess the point of the story is to not rush it like I did - wait, patiently... Join the different yahoogroups for the home quilting machines and check your Craigslist in your area and areas you are willing to travel to. You will save a lot of money getting a complete system used.
