The real question about getting into 40k. Why not just buy a 3d printer and print your own figurines? It should be way cheaper, you get a 3d printer, and I'm sure people have made 3d renders of all the models. Or scanned them using a 3d scanner.

At least in Yugioh you can make a competitive deck for less than 60 bucks. Chain Burn ALWAYS does good. No one sees it comming, few people have sides that work vs it, and people hate fighting it. xD
