Where are some good places to start looking for vintage Oakleys, preferably from the Mad Scientist era, and which places should I stay away from?

Where are some good places to start looking for vintage Oakleys = Here
Which places should I stay away from? = Everywhere else until you are able to spot the fakes in the models that you are looking for.
There is a ton of convincing fakes out there.
A fake posted here for sale would last about 10 mins or less before someone spotted the fake and called the seller out on it.
Anyway, welcome to the OF and to your new addiction.

I say stay away from Oakley's entirely. There are less addictive and less expensive pass-times such as meth, heroin, crack cocaine, etc.
