Cheapest And most RELIABLE domain registrars

GoDaddy

Good specials and fast email replies

Well, the usual reply around here is go with Enom. Almost anyone here (including me) would be happy to set you up with a reseller account.

GoDaddy has a mixed reputation... Enom is tops.

I agree with Matt it is GODADDY!!!

Godaddy AND Enom..
No problems with either one of them..
Only issue with Godaddy is that sometimes registered domains may show as available..
Happened a couple of times..

I agree with Red, enom is easier to push and godaddy has better specials. Both are top quality

For me:

Enom (by a mile), Godaddy, namecheap, Registerfly.

My first choice would be GoDaddy.com, cheap and features-packed!

Can't beat enom at the moment
