Signed by's

I've got that itch again. Just in time for the holidays. I'd like to trade/trade and buy for a new signed by card poster. The following is what I have at the moment;
UFC 64, 102, 107, 108, 115, 116, 118, Fox: Evans vs Davis, 148
WEC 41, 50
Strikeforce Heavyweight Grand Prix: Silva vs Cormier
I'd really like a rare one such as BJ Penn vs GSP2 (might be impossible). I am open to mostly anything, though. Please PM me with thoughts.
Thank you.
