eBay Camera Buyers Beware

I’ve had a decently positive buying experience on eBay when it comes to old cameras. I’ve purchased six cameras and four of them arrived in great condition just as the seller stated. But I was disappointed with two of them.
In both cases, the seller stated “Camera is in good working condition.“ Now generally, if I see that I’ll assume that the camera is operational in every aspect and that I won’t have to pull it apart to fix it. But I guess the phrase “good working condition” is open to interpretation.
The first camera had a screwed up rangefinder with sticky joints and a half-silvered mirror with far less than half the silver left on it. I got the sticky joints fixed, but the half-silvered mirror is probably worth more than what I paid for the camera — so now it’s a nice little viewfinder camera that has to be used at f/16 to ensure focus.
The second camera (which I just received in the mail) was in far worse shape. The latch mechanism for the film compartment door is totally beefed up. It holds the door closed as long as you don’t touch the camera. And the viewfinder… well, it’s more than a little foggy. Oh yeah, and the focusing ring feels like it’s running on sandpaper. So I’ll be pulling this one apart to see what I can do with it. But, for a $10 camera I’m not too disappointed — I just wish the seller’s description was a little better.
The point of my whole rant: “good working condition” on eBay doesn’t always mean that the camera is in good working condition. Many times, the people selling the camera know nothing about cameras so they really wouldn’t know the difference. Anybody else have bad experiences with eBay camera purchases?
