I took a step closer today, ordering a reprint of a user's manual for a #10 Cirkut from Craig Camera on the big auction site. Will be good to have some familiarity with the unit, whenever I buy one, before it arrives.
Jamie, I may take you up on your offer of Madison. My g/f and I are going to a BMW motorcycle rally in Duluth MN in August, as a vendor because I wrote a book on motorcycling with my (very young at the time) son. Madison is sort of on the way, or not far out of the way, and I have friends there that would enjoy a visit as well.
Will stay in touch, unless the Cirkut bug dies, or is killed off by a complete lack of film. But been pondering it for a while, so....
