I only have one UFO ready to quilt, but have another one that is close--so my solution? Since I don't have the money to buy a long arm (and with 2 small boys, don't have the time to get to the machine very often!) I rent time on my LQS long arm. It's very reasonable--3 hrs for $35. I only use it when I need it and don't have an expensive machine gathering dust when not needed.
Check with your LQS or some local longarmers--they may be willing to train you on their machine and let you rent it.
