I use <a href="http://namecheap.com" rel="nofollow">http://namecheap.com</a>. I have for many years. They had issues with a ddos attack a number of months back and handled it gracefully; ie. the owner was continually posting updates on the forums and helping users individually.
<a href="http://nearlyfreespeech.net" rel="nofollow">http://nearlyfreespeech.net</a><p>I am a big fan of these guys. Their technical knowledge is top notch and their pricing plans are perfect for small websites. Heck, I even remember them emailing me letting me know that ICANN fees were going to go up, and I should thinking about renewing my domain name before the price went up. Talk about customer service.
I use Dreamhost. That's where my hosting is and registration is $9.95/year with free privacy. I've never really had any problems with them. They can handle the Digg effect and their customer service is decent.
I use gandi.net for my .com, .org and .net domains. Their interface is great, but I can't comment on their support because I've never had a problem =P<p>For .ca domains, I use easydns.com .
Domains are pretty cheap anyway, doesn't matter which one you use.<p>The cost of the it is probably a few orders of magnitude less than the time you need to spend to come up with a good domain name. Thus, it's really not worth it to consider domain price as a decision factor.<p>Now, as far as functionality goes, namecheap.com is pretty good.
Been using <a href="http://domainsite.com" rel="nofollow">http://domainsite.com</a> for about 5 years now. Low prices, not nearly as much BS as GoDaddy. Sorely lacking in the user interface department (again, not as bad as GoDaddy), but aside from that I've never had problems with them.
I use Prosite.de for 3 domains, they host the DNS for me only. If you are german you could too.<p><a href="https://www.prosite.de/member.php?refid=5000140259&s=ma" rel="nofollow">https://www.prosite.de/member.php?refid=5000140259&s=ma</a> (Affiliate link)<p><a href="http://www.prosite.de/" rel="nofollow">http://www.prosite.de/</a> (Non affiliate link)
Once a long time ago I saw that DJB recommended www.joker.com and I've been using them for the past 5 years. They're not the cheapest (it's been $12 a year since I started using them), but I've never had any problems. The web UI is fairly simple to use, and they don't spam your email inbox.
if you're still not totally opposed to using godaddy, someone just sent me this great deal... $1.19 per domain:
