Odd, I think Evolution 2 is just uncommon here, I can usually find it for about $15 or so. It's less common than the first, but not rare.
I think there's only a handful of games I'd pay over $50 for. Skies of Arcadia, some of the less common Capcom games, and if I got RE 2 and 3 for $50 combined I'd accept that.
