Ok, so I was a little fed up with the
http://fo2238.fodev.net/wiki/Merchant page being out of date. I've taken up more to trading with merchants for weapons rather than spending days farming out blueprints just to find useless crap like super stimpak
Long story short, I've been trekking across the wastelands to document what most merchants are interested in. I'm lacking a lot of information, but what I do have is far more accurate and detailed than the current wiki page. Particularly, I am missing who buys energy weapons entirely, more detailed information on resources (someone told me pretty much everyone buys gecko pelts, while my "resources" i was selling was just good metal and sometimes gunpowder) I am posting this information share with everyone, even though it would probably mean more competition at the merchants for myself, I am most interested in discovery and sharing of information.
Please excuse the extremely poor formatting and vagueness of some of the descriptions, I was basically writing entries into a notepad document as I came across them, over the spread of a couple of days, so there are some rather large inconsistencies.

Again, this is lacking some information such as a more detailed approach of what "resources" (I just used good metal parts) and energy weapons entirely. I may have skipped a check for big guns in some of the places as well (dying and losing what few big guns I did have didn't help). Oh and a special note, be wary of what merchants are listed as selling, as player taint can be misleading. Whenever I say player taint, I just mean it seems like weapons that players have sold to the merchants. Typically if the weapons are 100%/100% I assume it is a standard item the merchant restocks, although i didn't always check thoroughly.
Oh special thanks to hoot/miklos, who killed me, but then let me pick stuff back up and keep testing (even showed me a good merchant I wasn't aware of in broken hills)
If anyone is interested, they're free to add to this, edit it, make it available on the wiki, etc. I might get around to editing it and cleaning it up for consistency, but as it is now it is a jumbled mess that I wrote up as I took information.
