What is best way to market and sell my premium domain?

[ideDomain]

I hold a premium domain name, IDE.com. Most three letter domains go for a pretty good price. I have looked at Ebay, Sedo and Godaddy. I am a little shocked at GoDaddy's commission of 30%. Sedo's seems to be less than that but still 20%. In your opinions are these services worth the commission? Also do they force you to sell at a set price? I want to maximize my exposure as well as my return after commissions. Where do the serious (business) buyers go to find domain names?

Thanks
