I just started getting into Netrunner and I'm trying to put together a couple of decks. These are the specific cards I'm looking for:
4x Organ Donor
4x Identity Donor
1x Promises, Promises
7x Bodyweight Synthetic Blood
2x MIT West Tier
2x Self-Modifying Code
9x Marked Accounts
1x Project Consultants
I'm happy to buy any those cards, though I don't really know about prices; we'd have to discuss.
If you're after other Netrunner cards, my available cards are listed here: http://www.netrunneronline.com/profile/497/?p=collection
I also have a lot of MtG, mostly pre-Invasion, but way too many to list. If there's anything particular you want, I can look for it.
