Hello, just came across this and thought I'd weigh in. I'm the person who brought the camera to Atlanta Celebrates Photography independently of Polaroid in 2001, and for the Polaroid Roadshow in 2003. (nice to hear I left satisfied customers!) I have rental and film prices as well as contact info on my website: http://www.mammothcamera.com.
More information on the Mammoth Camera Workshop I'm doing with Tillman Crane in Scotland next May: http://www.inversnaidphoto.com/mcwfinal.htm
We'll be using conventional film only (no Polaroid) on the 20x24 there. (a loaner Lotus)
