Many people have extolled the virtues of Ebay since it's inception in the 90's. The best thing about it, from the viewpoint of a 20 something, is that it finally allows me to fulfill all of my childhood dreams of owning totally useless things.
As an adult, I have found that I have a complete lack of control when it comes to using Ebay to find things that I wanted when I was a kid. And now that someone had the bad vision to give me a PAYING job, I've been able to do my best to hunt this stuff down.
