I have a Cricut and I like the machine a lot. I use it pretty often and as long as I have the cart I am super happy.
My favorite tool though is my Sizzix BigShot. It is really versatile. You can use framelits, sizzlets, regular sizzix dies, bigz dies, embossing folders and i'm sure i'm forgetting something. It's really easy to use, and not terribly expensive and the individual dies are priced nicely and unlike Cricut you don't pay for cuts you won't use.
Have fun with whatever machine you get!
