Or does everything just go on ebay?

I go to them, whenever I see them, but I can't base the behaviour of the rest of the population on what I do (otherwise it would be a car-less, vegan, perfect world...) I have a few q's:

Has anyone had a successful one recently?
Is it worth the hard work?
What items are good sellers?
What things are just a pain in the hole?
Do you go to them? What stuff do you like?

Note: I have read the existing threads on garage sales, and found them really helpful. I'm just looking for some different perspectives. Cheers.
