A friend of mine who I grew up with (and the primary reason why I'm so into music / vinyl) keeps a fantastic blog where he hunts down rare, import, and beautiful album artwork / packaging. Here's an overview from his site:
The overall guiding purpose of this blog is simple and unique: SixtyWatt is completely devoted to finding that special edition, that tour-only CD, that autographed pre-order that addicts like myself salivate over. This is the place for those who still buy music, who own a turntable, and who routinely pay overseas conversion rates.
Stop by SixtyWatt to learn more. He's also got a great list searchable online record stores. Happy hunting!
