"Cybernetic Beetles" for Sale. So far I have suppressed my normal urge to start every new army the day it hits shelves, and one of the things that has helped is the most interesting build, the scarab build, is kind of tough to do.
Thanks to Puppetwar.com there is now a pretty easy (and cheap, 5 euros for 5) solution to the problem of no scarabs. I've seen some guides on from the warp on how to make a scarab mold though even the author admits its not easy to do.
One day GW will realize how much money they can make if they actually sell the models in the codex. Until then, I hope more places like Puppetwar give the market what it's asking for.
