Lucky them, I cant imagine selling an army of my painted models, and quite frankly I doubt anyone would want them!
I also tend to use bone/dhenab stone as a replacement for white. It is a lot easier to work with, and I use white for final highlights. Sure it is a little dirtier, but looks more gritty.
Quick rules query for the eldar players on here. Swooping hawks can hit vehicles on 4s with grenades, does this apply in hand to hand against dreadnaughts? My first thoughts are no, but one of my group was trying to claim that they can.
