I check eBay several times a day and I can say the "average" price of a classic Mac is $100 bucks. I just checked, stopped counting at 22, but all but one are over $100. Sure, you can find units for $50, but they usually have a problem (or no keyboard/mouse). More often than not, SEs, Pluses, etc are posted for $200, $300, $400 dollars. Not to mention, the ones you might find under $100, you usually have to pay a good $30-$40 bucks for S/H. So you end up paying $100 anyway for a broken Mac.
