Gandi.net is awesome. (not affiliated, just a happy user)

joker.com, inwx.com ,namesilo.com, register4less.com, epag.de, iwantmyname.com, hover.com, Porkbun.com, www.nearlyfreespeech.net

.name domain isn't available in some of these, decide to use inwx.com

namecheap.com is great (always good prices). Obviously, never go with Godaddy.com (rip offs)

We've been using joker.com for years.
