I put two Epic 40k auctions up on Ebay on Sunday. I have put up both a Space Marine and Ork army.
I found both of these in my Warhammer box when my wife made me go through it so we could save space. It helped a lot actually, as I found these things to sell and I was able to assess what I have.
On an unrelated note, I found my old bitz box. It's got parts from the original storm guardians sprue, with a guardian powerfist, chainsword and powersword as well as some other goodies. For some reason it has a ton of Chaos bits even though I've never played Chaos.
