Best and Worst eBay/Craigslist/swap meet parts finds - what you got??

[C10agent]

I was curious what you guys have found of value that others have overlooked. I was able to get all my autometer gauges for my cluster build about half off retail on eBay. Some people simply don't realize what they have and it is fun to take it off their hands. I am always searching eBay and Craigslist for whatever I can find. I swear I have a problem and the wife just looks at me funny when I get excited about a good deal on a factory radio. Anyone else here share my obsession and what have you guys found???
