I'm on the 1&1 bandwagon too. They're EXCELLENT. Great fast speeds, unbelieveably cheap, tons of bandwidth, and outstanding customer service.
A good example would be that I experienced an outage that lasted about 30 hours and recieved an immidiate e-mail telling notifying me of it and that it would be fixed soon, I then recieved another e-mail explaining that they had a complete RAID failure on that server and they credited another month of hosting for free to make up for it. Now what other company would do that?
Stick with em. They're outstanding.
