Definitely try Parked.com. I moved a few high-traffic, low conversion domains over there and they make 2 - 4 times the revenue as with Sedo.
I'm not sure, but I think Sedo limits you to one click per visitor per day, while Parked has no such restriction. I have a few domains that get 3 - 5 uniques a week, but with Parked, I might get 5 or 6 clicks from a single user, generating $2 - $3 in a day.
Nice
