Ah, right, with that I should probably mention:

Poe will be able to repair/maintain weapons and equipment for people too stupid to do otherwise, :P and due to a generous donation of special technology from Mr. House, he will in fact be able to make custom weapons from scratch. He's paid by commission by House and Tenpenny, so the only thing he needs are raw materials. I was going to have him hand out a shopping list of valuable materials for the party to scavenge for while out and about.

So if you can think of Custom Items for a particular location, that's great. If there's a particular unique item you specifically want your character to have though, just run the request by Poe. That way you can make random cool things for all the locales that you might not necessarily want, but someone else would be interested in.
