The KO really isn't that bad for what it is. Stickers on it totally suck though.
Don't kid yourself about a real G1 Raiden, if you want even a
moderately decent one without the box, plan on spending
several hundred dollars at the very least no matter where you buy it. If this sounds out of reach for you, settle for the KO for now.
I plan on owning one someday in the future but I know damned well it will be anything but cheap unfortunately.
Welcome to the boards by the way!
