I am currently selling iHateSusanBoyle.com on E-bay I think it is the best way to approach domain selling due to using E-Bay as the third party of the transaction. Is there any other way to approach selling domain names and websites that will work securely on the same level?
Try selling it here on DP. Don't use ebay, domain names dont get a lot of attention and you'll have to pay the listing fee if it doesn't sell. I've been down that path before.
I don't recommend you sell at ebay coz there are few chances to get high price. You can sell it at sedo. For security measurement,you can use escrow service.
Use Sitepoint (http://www.sitepoint.com/) to sell your domain. I usually get better result from there.
