I use namecheap, been using them over 3 years, they are best and friendly in the business. Sometime you ask for coupons and they just give it to you. What more do you need a domainer
.
As for godaddy, they are fucking biblebelts, They once refused to register a domain, because it insinuated like a trade name, a week later I see the domain show up in their parked pages. What ever. Moniker I tried while ago, it was too complicated for me to use, specially when it came to domain transfers ect. So I dropped it.
I will go with namecheap for domains. reasonably priced, good customer service.
