Thanks again to DolphisMaster for the tip!
Profiles In History has one of the He-Man "Hero" costumes up for auction! Though it is incomplete, this is still a beautiful example of the suit. With an estimated value of $2500- $3500, I only wish I could afford it...
Here's the description from Profiles:
