So here is what I will be using for my sorcerer (or Herald if I start a Daemons army).

SOLD OUT - Vorneus and the Crawling One - Reinforcements Box Set - Stray Ones (x2 figs) French Version - HELR04EG

I got it in today and the scale is good. Just a hair bigger than a Chaos Warrior. The box came with both figs in the pic. The second one would make a nice Nurgle sorcerer/herald.

I'm probably going to mount the Tzeentch-looking guy on a disc.
