I also have both the manual and Big Go Electric. I had the manual first but after yrs of cranking felt I deserved the Electric. I would go with what you do most...If you work with blocks go for dies 5-6-8 inch, Ohio Star is nice, Smaller blocks 2 1/2, There's triangles, tumblers, Maybe buy when you have a specific quilt in mind. Like most we buy thinking we'll use certain ones and they lay unused.
