I'm happy with
http://namesdirect.com/
----edit
what the hell?!
$30 to register domain??? it used to be $9 or something
I renewed few domains few weeks ago with old price so I'm a bit confused with this new one
----edit2
well.. actually I think they transformed into
http://www.mydomain.com/ but I still log in with namesdirect site and can renew for $8,50
