I've had some problems with Godaddy, specifically when trying to move domains that had private registration enabled away from them. It seemed they tried to make things difficult on purpose to make me give up and keep the domains with them.

Also, they used to spam me with "good offers" and when I was going to order a domain from them it was not a very straightforward process. They kept asking me if wanted a lot of nonsense services they made up, with obscure names ("premium platinum business registration"...) over and over again.

Not recommended.

Not had any problems with Godaddy at all! Fabulous are good as well, they have a quick and simple DCC.

Whatever you do stay away from one and one. I would rather give up domaining then deal with them again.

123-reg.com all the way for me.
