I made the mistake and regged a couple of domains with 1&1 also because Sedo has banners..so I thiought I give it a shot, and thats also where you get linked to by Sedo if you need a registrar like many new buyers, and I can say that 1&1 is probably the worst registrar I have ever used. If someone buys a domain from me and wants it transferred to 1&1 because he saw the banner at Sedo the transfer is going to be long and painful. Or even worse if the domain I am selling through Sedo is at 1&1, for the sake of providing customers with good service and fast service for those that are already customers I think Sedo should look to promote those registrars that have the easiest and best domain handling... I think if you want to be taken seriously as the best marketplace you cant promote a registrar that is that bad..
