GoDaddy, Namecheap, Hover?

First of all: Never register your domain through the hosting provider. They are there for hosting, don't waste your money on giving them the power to control your domain. It's yours. In a dispute and with a bit of bad luck they remain the register on it, or the tech admin, and move it, lock it, lose it. It's just not worth it. Go with a registrar and not a shitty reseller.

Examples are Namecheap and Hover, go with them. They're easy, affordable, and give you control over the domain, dns, whois protection, etc.

Don't go with GoDaddy: they're fucking assholes. You will be regretting it in the long run.

Any other company you would want to add to this list?

I've used Hover in the past, and I think I still have a few domains with them, GoDaddy I've blacklisted, what a fucking terrible service provider that is. Namecheap has been the most interesting so far, but I am afraid once I see them scaling their services that I am not super comfortable with them anymore either.

namecheap though, is the recommended one here.
