I already have one, but I know other board members have been interested in the Alto's QuiltCut. Anyway, there is one (I think) on the Denver, CO area craigslist titled "Alto's mat cutting System". They're asking $50 which is an excellent price, especially since it appears they didn't use it. I'll try and attach the link:
