I have the Q-snap floor model and love it. Even taught my 13 yr old dgd how to do utility stitching on the yellow brick road quilt we made together. She quilted on one side while I worked on the other.
I must say tho the Ulmer frame you have just introduced me to looks fantastic & seems to work much the same way but with slightly easier set-up.
I have also used a large hoop in my lap which is good for more portability but I'm thinking about getting the one on the lap stand that swivels rendering it hands-free which would be a bit better.
Let us know how this all turns out.
