Just sold some army books on ebay. Highest bid was for Daemons of Chaos, then Dark Elves closely followed by Orcs and Goblins (only 1 pence between those two!). Bringing up the rear was Wood Elves which went for a very paltry amount.
So for all those Daemons of Chaos naysayers (who include myself), this appears to be the most desired army book out there
Clearly we aren't getting through to people...
