Yep, what he said.
My wife has a 6x12 and uses the sure cuts a lot software which can do svg.
The cricut uses a tacky adhesive cutting mat that wears out over time, some other cutters don't need mats. Also the blades will dull with use. Both would probably need replaced with a used one.
I could probably bring it down for a demo.
Out of the other devices on the market, she wanted the craftwell ecraft cutter most. It doesn't need a mat, can be fed from a roll of material, and works with the same sure cuts a lot software.
Also I've seen someone in thingiverse maybe use a Cricut or similar
cutting bit in a Makerbot or Mendel.
I have a silhouette sd and it is wide open, has an illustrator plugin
and it's software imports vector artwork quite well!
A few folks picked up cricuts from Craigslist since most people seem
to upgrade to larger units.
I'll try to find the Cricut hacks.

I've wanted to make a tool to mill copper-clad for pcb's with a Dremel.
