The domain listing services didn't seem like the right venue for a premium domain.  We worried that potential buyers would have a hard time finding us, and we didn't really know what the right price to charge was!

For this reason, the auction model was appealing, but -- of the online auctions -- only Sedo's new "premium domains" auction had any real attraction for me.  The others didn't seem like the right venue for a high profile domain.  The offline domain auctions of Moniker and Domain Roundtable, despite being kind of a backward way to sell online property, were clearly higher profile events where some qualified buyers might congregate.

Moniker has a good grip on the premium domain aftermarket, accounting for close to half of the sales on DN Journal's 2007 list.  They are the big player in the industry.

On the other hand, Domain Roundtable has some fantastic ideas about how to make the industry even better.  I love adding the live component to the auction -- which would make it much easier for entities who aren't professional domainers, who might have a legitimate real-world use for a good domain to buy the domain of interest to them -- , and wish Moniker had something like this.  I liked their transparency, too.

But, there were just too many unknowns about Domain Roundtable's auction -- as a first time occurrance -- to pull the trigger.  I also took Domain Roundtable's suggestion that we submit what seemed like a lowish reserve (in comparison with Moniker, which didn't immediately flinch), as a sign of lack of confidence in their ability to pull in the big numbers.

We chose Moniker's auction.

Note: We didn't have time to fully investigate the domain broker model, which I think might have been a very good fit for us, because I think a person actively pursuing leads might have been able to find some very qualified buyers.  Unfortunately, I didn't know any domain brokers, and the time constraints made it difficult to find out enough to be truly comfortable.  If I had another week or two to make up my mind, this is where I would have spent my time.
