Every so often I read somewhere about people who don't like ebay for whatever reason or who refuse to use it. I can't understand them. I've used ebay to successfully buy out of print CDs and to locate rare spares for my '87 RC car, all of which would be virtually impossible to find otherwise.
It's true that sometimes you'll see idiots paying above retail for brand new gear simply because they don't do their research. That has never happened to me, mainly because I'm a snob when it comes to shopping - I check the specs and prices of just about everything I buy. I'm not a power user - I don't buy and sell my entire life there, but I do like to bargain hunt too. I'm particularly happy with my most recent purchase, which somehow slipped under everyones' radars.

Now if only I could find auctions like that every day!
