I have a domain registered with registerfly, and man the first month was the most horrible with them, there DNS server was most of the time down, I sent them a couple e-mails and they where very slow to reply back, if they have a problem they are very hard to admit it. I won’t do business with them any more, I just keep my domain that I have with them, cuz I am afraid if I decide to transfer it I would see hell with them again. My best buddy for me is yahoo, they are fast I never had a problem with them.
