Today I moved all my domains to gandi.net.
I wanted a more secured place for my domains, they provide several services I believe they shouldn't be expensive, such us whois contact privacy, which you can have for free here.
They have a no bullshit agreement, and people recommend them in different communities I trust.
The change was executed flawlessly, thanks also to my previous domain provider. The domain price is good enough.
They support several free software projects and organizations I feel identified with.
I like when companies have a declaration of intentions, I think It's honest to do so.
UPDATE: On top of that they have a good technical support team, I had a small problem and they solved it nicely and instantly.
