There are a few people out there already doing it Caro. I know ive heard from some people as well, that their local shops have them, and if you go there you can use them for a fee etc.
I think its an expensive tool for the occasional scrapbooker and would only be for someone serious to buy for themself. So essentially, there would be a market for it. So having a wide range of products would be ideal.
On the other hand, there could be loads of other people thinking the same thing, I know when Sizzix first came out, people were charging quite a bit for the cuts, now most have come down a fair bit.
