What domain registrar do you use?
I've been looking for a registrar for a startup's website, and figured that y'all would know what registrars are better than others.
I'm mainly considering price, but please post about any of them :)
DNSimple has been solid. Easy to understand UI and reasonably priced private registration and other nice features like automatic dns setting templates for various services like gmail etc..
Domain registration costs are pretty standard at $10-$20/year. Price should not be a determining factor in your decision.
Namecheap. Cheap, decent UI, good customer service.
