Registrars?

I've been with Omnis for years (they were awesome) and they were bought out by JetHost. The transfer took down a bunch of clients. Now I'm arguing with them and they don't offer an online guarantee or a refund. I have to deal with clients whose websites were down. I'm really upset just because I have never had to worry about this. Anybody have cheap reliable registrars? My fave never showed in google, so I figured I'd axe the community if anyone h
