This is a really well laid out resource, with excellent ideas inside. I've given it 5/5 even though the author hasn't suggested prices as I think black market prices can be as crazy low or ridiculously high as you want; it's not as if the market's regulated! I've already pulled several of the items out of the list and put them into my current campaign, and will be dipping in again and again now that I have a fully stocked black market to access. Excellent all round.
