I'm one of those misers who buy everything used, and I bought an old DE army for peanuts just after 8E came out. Guy was cleaning out his closet, which is where one finds the best deals.
I've been playing Chaos, so I didn't really look at it in detail until recently.
It's chock full of old pewter. Incubi, scourges, wyches, special weapons, Yorrick grots, mandrakes, 2 Taloi... Basically, all the stuff I couldn't afford when I first got into 40k because plastic was the only thing I could afford.
So I'm doing the happy dance. Pewter FTW!
Worry not about Chaos; it is the used 40k market that shall be thy temptation.
