Warhammer 40,000 Stuff (recommended sources are The Hobby Shop on Grand or the online store at Games-Workshop)
Unless I somehow get all of the firearms listed on the firearms section of this wishlist, I am likely not to work on building any new armies, only working on completing existing uncompleted armies, which would be limited to my Orks Speed Freeks army, despite the fact that I don't yet have one model of it.
1. Imperial Guard
2. Forgeworld Stuff
3. Chaos
4. Space Marines
