Serious domainer (buying + selling domains for a living): Moniker or Fabulous.com - Both are designed to handle mass updating of domains easy and for optimal parking. Monikers support is 9-5 and fabulous is invite only. Both are still fantastic.
Everyone else: Name.com :
Why name.com? Outstanding support staff, Free privacy, Low prices, Great reputation in domaining community. Outstanding security.
You are right to not use godaddy. They are pure evil, see godaddysucks.com for more proof. I recently moved all my domains off of them just to be safe.
Also, do not use a domain registrar thats tied to a host ( dreamhost or otherwise ) - While they may be a good HOST, they can not simply compare to a dedicated registrar. I do believe they are nothing more than opensrs resellers anyways so their involvement is limited and should you have a problem, prepare to jump through quite a few hoops.
I use 'moniker.com', I'm pretty happy with them but I only register my domains there, everything else is on my own servers, so if you go for hosted DNS and other goodies I can't tell you much.
Moniker prides itself on never having lost a domain and their prices are pretty good.
Previous experience would lead me to stay away from bulkregister/enom, godaddy and netsol.
