Wow at people recommending GoDaddy for a registrar... do you work for GoDaddy or something? GoDaddy has a horrible interface, always trying to add upsells that you don't need, takes forever to update nameservers etc... Only good thing about them is the $1 domain promotions they run sometimes. Oh yeah and WHOIS privacy costs like $10 there? Go for internetbs.net or namesilo. Both have FREE whois privacy. Nameservers are configured near enough instantly so no waiting around. Cheap prices... like $9 for a .com Good API Fast checkout process without all the shitty upsells GoDaddy and other registrars pressure you into buying Interface is so easy to use and navigate
nobody mention name.com? I think name.com is quite good and secure, I've been with them for about 15 domain bought and 2 years of running. Their CS are also good and helpful
I use internetbs to buy domains as they are cheaper and their support is awesome. They do not have hosting which is good for me because I use Hostgator .
Eurodns.com is one of the best registrars of domain and you will surely enjoy their services provided. The best deal regarding this service is this that it is available at a very low cost.
