I have about 150 pieces for trade here, the majority of them from the first four sets (Rebel Storm, Clone Strike, RotS, and Universe):
http://www.bloomilk.com/Collection/Trades/gwekWith many of those old pieces getting new life in the upcoming virtual set(s), why not look into getting some of them?
Although my own wants list is pretty short, I'd also trade for cash or pieces from the most recent Dungeons & Dragons minis set.
I will entertain ANY reasonable offer (especially if it includes a VR, even one that I don't specifically have on my list).
Finally, if you're good with customs, send me a link to some examples and maybe we can work something out.
If you see stuff on my trades list that interests you, get in touch with me and let me know. I bet we can work some sort of trade.
