Hi S.,
I have sold and bought quite a bit on eBay. Mostly collectible Barbie dolls. But please be careful. I paid and accepted payments through PayPal. Twice someone tapped into my account. I was then sent e-mails from someone saying I won a camera and owed $300. It's just the usual, never give personal information and notify eBay immediately.
My husband on the otherhand is very different. He is currently selling oriental rugs, collectible vintage fishing creole, jacket, etc. Like the person below, collectibles are good items to sell. He also sold a car last month on eBay and will sell another one next month.
Good luck......
