I have a cricut create and I love it! It's basically a printer, but cuts instead of prints images. I use it for most of my lettering and tons of other diecuts.
I'm not sure what the difference between the imagine and expression 2 are. But it may just be size. Mine only cuts up to 12 by 6 inches, where others cut 12 by 12 paper.
There are some pictures in my gallery where I've cut stuff with my cricut. All the lettering and some of the fancy stuff. I'm not sure how to put the pics in the post like other people have.
