Kool Stuff is your only chance.
http://www.koolstuff.caJeff is an amazing guy to deal with, be sure to tell him I sent you there.
I have no clue what kind of stock he has, all I know is that it never compared to mine, he doesn't seem to "buy" collections, only takes them on consignment.
Nothing wrong with that, but it's harder to trade or work deals with people on things when you don't own them.
Give him a try.
Outside of that, there's always the JoeCanuck.com store, I could meet you at TRU or something. ;-)
