after getting better on my domestic and getting used to moving the quilt rather than the machine, I decided to go with the larger sit down Handiquilter so that I didn't have to change methods. I was able to get on it same day and do the same level of quilting (if not better due to a better machine).
I was concerned about a large learning curve on a long arm (along with the space issue). In trying them at quilt shows, I just liked the sit down better.
