Here are the Budget army lists. They are all 1500 points for under $300... except guard... that one is $306. Stupid 5 point guardsmen! We have skipped a few armies on purpose. Necrons because they are incredibly easy to build cheaply... and because their codex is so weak right now. Dark Eldar because the one or two "competitive" army lists are expensive (raider intensive) and anything else has a tough time in 5th edition. Orks & Marines got skipped because Black Reach makes them super easy to build cheaply. We also skipped the all metal armies for shipping costs & conversion ease. It's not tough to build a 1500 point GK army cheaply. I might see if I can do something with sisters though.
There are a couple that I'm going to reserve space for because I don't have them typed up yet!
