My pocket tin ran me about $50, maybe $60. Admitedly, I do carry more than the PSP, and the tin is a little bigger than an Altoids tin, but it is by no means hard to carry. Price would be lower now if I started with a PSP, but this is older than Doug's kit.

And it isn't arbitrary. Have your priced the PSP and a good pocket knife? That is what most of us would consider the bare minimum, and if you are paying less than $50 bucks before tax and shipping for the two, someone got a deal.
