Hi Brewsa,
unfortunately I can't help you regarding a hand quilting frame like the EZ3 you've mentioned. I can't use such a frame because I only quilt in one direction - towards my body - and I have to turn my work. For that reason I use a quilting hoop with 18" diameter on a stand (Jasmine) and I love it. I do all my quilts in it, small and big ones. The weight of the quilt lies on the hoop, not on my shoulders, and it is really relaxing to work that way.
Did you try the Search-function here on the board? I think there are many posts regarding hand quilting frames and maybe you find some good tips.
