Best place to buy used iMac <$500

What is the best place to buy used iMacs? I need to replace my in-laws g5 iMac. Power supply just popped and its not worth replacing. Looking for a reliable refurb company, and something under $500.

I bought a less than a year old MBP for $700 off of Craigslist. Look there first. Just be sure to screen the person first. Ask questions.
