I picked up a Devastator with Crazy Devy parts and must say I am mightily impressed with the upgrades. This is one of the best 3rd party products I have picked up as far as upgrades go. Really adds alot to the figure. Especially the Forearms and legs. I suggest picking up these upgrades for any Devastator fan. I have seen there are other upgrades. How do they compare to the Crazy Devy stuff?
