Nice topic. I am currently making a couple of kits up, myself.
I like tiny kits. Currently, I am playing with one of those Doug Ritter pocket kits.

This afternoon, I gutted and refilled my huge first aid kit, carried in one of those folding Nam pattern military nylon kits. It took me several months to gather the partsd, and it still is not finished... <img src="/ubbthreads/images/graemlins/frown.gif" alt="" />
