Ahh, a fun way to color prints. I got one of these kits a couple of years back and had a blast playing with it. I think I still have all of the colors hiding in the cupboard behind some things, might still be viable.
Konica Flashcube adapter. Allows you to use a flashcube on a hotshoe (or cold shoe since it also has a pc cord). Small; about 1x1x2 (inches). Require 15v photoflash battery. Should not be more than $2-3 to ship via first class in US.
