I would do E-bay for stuff that is easy to ship. I used to be pretty active buying and selling vintage model airplane stuff like engines and old 60's and 70's radios and parts. Big stuff, like full frame sets and bikes are easier on Craigslist since you are dealing with a local market, and shipping isn't as involved. You will probably get higher prices on E-bay, but listing fees, and crating and shipping costs can eat into that.
