I am going to follow this thread, because I am very interested in the Brother Scan & Cut too. I saw one demonstrated. The lady who did the demo was using several computer programs (all of which she sold) to get the picture to the machine for the cut. It looked like it was going to cost over $1000 to use it her way. I really want to know what the machine does on it's own.
Edited to add:
I haven't watched these yet, but they could hold the answers.
