I have an Accuquilt Go! myself, so probably would not be interested in buying pre-cut kits.
I have in the past purchased pre-cut quilt kits for my sister (the older JoAnn's Fabrics type) off eBay and might consider that again. However, it would need to be a complete kit with instructions, borders,etc.
Are you planning to sell complete quilt kits? Or just sets of individual blocks? Have you checked out eBay to see what your competition would be? I have noticed several sellers offering this type of thing. The Yahoo! group for Accuquilt users also has a swap section for people who have different dies and want to swap shapes.
I would be concerned that the Go! dies might wear out from production cutting. Quilting shops usually purchase the Studio setup.
