I have the Studio II, the big heavy manual machine that's often seen in quilt shops. It isn't hard for me to turn the crank, and I have a place for it at the end of my long cutting table. It's much too heavy to move around. This works well for me, but I can understand that it wouldn't work well for someone with wrist or arm problems, or someone with limited space. I only bought strip dies for it. The dies are heavy too, and take up more space, but I'm happy with this setup.
All my dies are in half inch increments. The pattern for the next quilt I want to make is written for strips that are cut at 1.75", to finish at 1.25". I priced the strip die of that size - $270!!! - and decided it wasn't worth that much to me. (Boy, have prices gone up since I bought my machine.) But rather than cut all those strips with my rotary cutter, I plan to change the pattern to use 1.5" strips that finish at 1".
