Hold out for the Cameo! I find even 12 inches to be limiting sometimes, I would be so frustrated with only 6 inches to work with.
I got the Cameo Tool Bundle off of Amazon for $230 (NEW!) back in August. Add it to your Amazon wishlist and keep checking back, it goes on sale every once in a while! :)
(I would say add all of them, tool bundle, vinyl bundle, ect. to see which goes on sale first!)
