I am starting to contemplate building up a 3rd army and its sorta down to 2 choices.
Necron: Could be fun to paint but get boring fast with 50 warriors. I like the idea of inventing a really cool rusty look for them but am not sure. Also a new codex is looking likely so it might be fun to ride that wagon.
SMs: Vanilla marines painted for Salamanders or Iron Snakes. They are cheap due to the massive kits but I am not sure.
I still got to get the money together but with nothing more to really buy for CSMs and Sisters its pretty tempting.
