I'll second my vote for DNSimple. We were using GoDaddy before and we had an issue where they were returning faulty DNS records from certain hosts (which was such a pain to diagnose). After trying to deal with support at GoDaddy we were done.

We switched everything over to DNSimple and I'm happy paying them $3/month so I never have to look at another GoDaddy config/upsell screen again. They also have a status page (powered by Pingdom) http://status.dnsimple.com.
