Ask HN: Which domain registrar do you use?

Currently I am using a Dutch company to buy and manage all my (and my clients') domains and their DNS. Since our company is shifting to more international grounds and isn't based in The Netherlands anymore I am on the lookout for a no-nonsense competitive domain registrar service.

So far I've looked into all the big players like Network Solutions and GoDaddy but their lack of clarity, costs and bloated registration process really scares the hell out of me.

What service do you HN'ers use?
