I bought the SCAL before they stopped it. It did work, but not with my favorite vector program. I had to use Inkscape to save SVG. While I've never tried cutting fabric in the Silhouette, I can cut a paper design exactly where and how I want. It isn't automatic like scanning and having the machine do everything, but it can be done. I see that Silhouette does have stabilizer out, would have to buy it to see what it actually is and if it works. Most won't like the learning curve. I'll admit that. I do like a learning curve most of the time. It's good exercise for the brain.
I have a friend who is totally baffled by any learning curve. She does want the machine to do everything automatically so I can understand that viewpoint. Even with an automatic anything, I get a phone call.
I have seen the Scan n Cut in action. I got the store's Silhouette Cameo (unused to boot) at a really good price. I don't really do enough applique to warrant the expense.
