I was going to try to resist this new gadget, but today I got an e-mail from Sewforless.com saying their $350 item is on sale for $199. Then I saw matts on sale, small, med or large. If you were to jump in and get one of these Go Cutters, what all do you need? Eventually will the cutter parts need to be replaced? How large is this thing, does it take up as much space as my sewing machine? Is it heavy. Any input would be appreciated.
