If you measure value in decades and don't care about appearances then industrial supplies are always the way to go. The previously-reviewed McMaster-Carr Online Catalog is the granddaddy of all industrially-minded geeks, but their focus is on tooling and indoor industrial items. If I'm considering anything for the outdoors, Ben Meadows is the first catalog I pick up and the only other paper catalog on my shelf I use regularly.
In case you couldn't (or wouldn't *lazy*), we are here to provide the masses (but mostly ourselves) a place to catalog our media collection, whether it be books, DVDs, CDs...
And we're more than just that. We're providing a place for the packrats to commune and orate.
