I'm sure you've read all of the prior complaints about the figure. The plastic does feel lighter/thinner than other deluxes. However, he feels sturdy enough to me, but it is somewhat lighter. My only real complaint is the size.
However, I really do like the figure and would recommend him. His design is exactly like the game and that's a big plus for me. The paint apps are very nice and his alt mode looks great too. Overall, I am very pleased that I got him. It would definitely be worth it if you took Zodd's advice and picked him up for a little cheaper online.
Bottom line: In my opinion, if you're a fan of the games/going to play the game, then I think he's worth it.
P.S. I have WFC OP too. Although that version is better, I really like having both incarnations of the video game representations of OP.
