A member of my group who also buys a lot of HERO stuff has to come up with some extra cash by EOM so I'm selling some of his stuff on Ebay for him (see what happens when you get a big Ebay rating). Has several of the newer books (core, UMA, Ninja Hero, Star Hero etc) as well as a few of the older support books.
So if you're missing something, or just need a loaner copy give it a look.
