Try craigslist.
This...for anything local and possible stuff that's too large and too much of a hassle to ship.
I've used Ebay for years with great success, but you have to know how to word your ad properly in order to avoid future hassles.
For example, I'll try to list the shipping costs up front but I'll state that any international shipping will be calculated after the auction has ended and the buyer will be notified within 48 hours of the final cost.
I'll also put stipulations on payment, preferring PayPal to expedite immediate shipping, but I'll hold the item if the buyer is paying by check or money order, in order to avoid a scam of any kind.
Also, stating that the buyer has to pay within 5 or 7 days is good practice as I've had some people bid and win and then claim that they forgot that they even bid.
All that said, I've had REALLY good success selling stuff through craigslist. No fees =
