When the price of Kodachrome 25 started getting absurd, I sold my stash of around 40 rolls from the last batch. It made more sense just to shoot a larger format, if I didn't particularly need 35mm slides--nice stuff though.

I've got some Super-XX and Ektapan 8x10", 10x10" Haloid Industro as well as 8x10" Gr2 and 3 Azo, and 10 rolls of APX 100/120.
