Thus far I've been fishing around Amazon and eBay but before I go through with anything I'd like to know if anyone has any other suggestions. I don't really care that much about the case and stuff, just that the disc itself is in as good condition as possible and it doesn't cost me $100+ or something equally ridiculous. I'm seeing quite a few sales of supposedly "near mint" copies going for around $40-50 which I'm considering.
If there is any other place you'd recommend I look, I'd very much like to hear it.
