This is a pretty neat product. I especially like the continuous-feed idea.

I'd really like to do stuff that involves stainless. What would be the cheapest option capable of doing some reasonable sheet stainess? My wallet is cringing at the mere concept, but maybe I could talk a local hackerspace into doing it or something.

I've been meaning to build a CNC mini-mill for a while. I think that seems like a more practical option for stuff that doesn't require intricate cuts. And definitely more affordable.
