Last night in kama ad1 I saw a seller advertising to sell Earthbound Staff for 4k. I would've bought it, except I bought one from someone in LA a few months ago for 3k.
And @ Unendingfear above - the best advice I can give in the meantime is to lurk around the buy and sell forums here. You could do like I did and make a whole green shopping list and see what offers you get ... but that may be a bit more than most people are up for.
And I restate my vote that there should be one big green sticky for all campaigns. I'll try to write one up like I did this one if the powers that be think it's ok.
I sold Rocktail's stinger for 5k and Arachni's Scythe for 25k, both were people asking for them so I tossed out random prices so take that for what it's worth.
