Frankly I'd be afraid to try to sell anything big on ebay with all the scammers. I'd suggest putting an ad on craigslist and meeting the buyer in a very public location for the swap.
Fake money, Crimes of opportunity and the highly anonymous nature of craigslist transactions are why I've always avoided that site.
No need for alarmism, I've sold plenty of expensive electronic stuff on eBay, you just have to be knowledgeable.
Don't sell to people with zero to little feedback,
don't ship outside of the country you currently live in,
set up the auction so only buyers with a paypal account in your country can bid, don't accept any emails/side deals from people wanting to make the purchase "off the eBay books",
If the offer looks too good to be true, it IS.
Clearly state in the auction you expect the winner's payment within 48 hours
ALso, shipping with a tracking number, signature confirmation, and insurance, if after all precautions, you are scammed in the most unlikely circumstances, paypal will still side with you as long as you followed the 3 shipping requirements I mention because that documents you followed through with the shipping, if the post office loses them item, or the scammer claims they never received, their dog ate it, someone grabbed off their porch, its BS because USPS won't deliver without a signature.
