I have read Many reviews for godaddy for the quality cheap service they provide. However i have my domains registered with domainsite and have faced no problems till yet. Also they are more cheaper than godaddy too. So whats the reason godaddy is more popular ??? I have registered 13 domains till now all with domainsite.
Simple: advertising. Domainsite doesn't exactly have the same monetary umph as Go Daddy has to advertise their products. But they know what they're doing...I hope.
I would personally recommend domainsite.com and namecheap.com. I cannot stand godaddy.com. Infact, it doesnt even load half of the time, which is a pain when i need to update my ccTLD's. From what i have seen, domainsite seems more stable and a more reliable service to use. godaddy does have 24/7 phone support which is NOT overseas, but it is more expensive than domainsite. Namecheap is my favorite registar because they support unverified paypal which is basically what i have. I couldnt pay via paypal for domainsite. Rob
