Ask HN: What are the best places to sell domains?

I'm sure many people here are familiar with registering a domain for an idea you're super pumped about only to forget about it a few weeks later. At least a few times.. or maybe few dozen times. =|

Anyway, I've got quite a few names just laying around that I've accumulated over the years and have absolutely no plans for most of them.

Any popular marketplaces you could recommend? Not expecting to make a killing, just figure it's about time to save $5-$30/yr and maybe recoup some of the sunk money for domains which I have no plans for.
