I have an Expression (electric), Cuttlebug (manual) and I just rec'd the Creatopia (manual). The Creatopia can emboss (up to 12"), die cut (uses other maker's dies with the die cut attachment), cut with decorative edges..the list goes on. I like all three. If money was not an option, I would get an Expression because of the capabilities (can cut up to 23.5") and a cuttlebug for the embossing. If I was on a budget, I would get the Creatopia because of the many functions. The Superstore has a bundle (not available now) and the die cut attachment for a total of approx $250..
I guess it depends on what you want, but I use (will use, just got the Creatopia) on projects, cards and layouts.
