I have been trying to sell of some of my names using eBay lately, and to be honest, it is the only place where I get any interest... Having said that, I am not selling any really premium names like this one...
One thing I do notice is a real increase in traffic and clicks on parked pages when I have them up for auction, it is a great way to get some extra traffic, more than covers the listing fee...
Also, the fees are much lower than selling on Afternic or Sedo, so if you get close to what you want for a domain like this it must be worth it... I say this one is worth $100k
