If this were Porunga, I’d probably be more inclined to pay the $180, since I already have Shenron. Even still, $150 seems more reasonable.
Personally, I don’t feel like Great Ape Vegeta is a must have. Same with Shenron and Porunga though, to be fair. The Banpresto stuff is more than fitting, when it comes to getting proper representations of those characters on a shelf. Either way, they’re all back drop pieces.
