Does anybody know of a place online that sells old stock or used editions of the original "Real Book?" I'm a college-level jazz musician that has been looking for one of the originals for a couple of years now (half-heartedly), and would like to find one that isn't an exorbitant amount of money.

I've checked eBay and Amazon, but they both have ****ty editions.

Just wondering if anybody knew of an internet gem that could get me what I'm looking for. Thanks for the help.
Honestly, why do you need the original? They have the same songs as the new ones.
