I love Tech Pan and used it exclusively for some projects back in the day. A few years ago I went through a big acquisition stage and bought up as much as I could find at the time, at least 7 or 8 bulk rolls, 60+ rolls of 120, some 4x5, and probably 30-40 boxes of Tecnhidol, just as that was getting closed out. I still buy it in 120 and 4x5 when I find it and the price is right. I also still look for HIE in 4x5 (or 120) and pick that up when I can, it has a unique look.
