The Army is expanding already.  I have picked up the following items from ebay.

3 Chaos Warbikes - Primed, unpainted. < $20 (42% discount from retail)
11 Khorne Berserkers - Mostly Painter, a few parts missing(Easily replaced). < $20 (48% discount from retail)
20 Chaos Space Marines - Unprimed. < $25  (31% discount from retail)

All prices and discount percentages include the shipping cost.  I think its been a good deal so far.
