Despite there being a Masterpiece Optimus Primal toy, which is admittedly the ideal version to have, I really enjoy the original Ultra Class figure, even though mine is not 100 percent complete. I like him even more with a few custom paint apps, and because of a shipped cost that was only 30 CAD. I never intended to ever really have this guy, but couldn't pass him up, and, boy, am I glad i didn't!
