I had a Scan N Cut, and sold it after it spent months gathering dust. Its a good machine, and easier to sell if you have other crafty people in the house that like scrapbooking or sewing but the average software and not being PC connected got to me very quickly.
Recently I got a Cricut Explore and love it, much better IMO for the sort of things I needed like vinyl or paper masks (a4 sheets of tamiya masking paper are the best) simple but powerful software on PC (very limited support for smart devices) and super easy to use with a simple dial to set depth and lots of accessories available in NZ or Ebay.
Mine came with some sample vinyl so car stickers for the cars were the test bed, then i tried the tamiya paper and was stoked with the results.
