I have been using Gandi for several years and been very happy with their service.

They offer domain registration in .com/.org/.net/.biz/.info/.name/.be for EUR12 a year (about $14 dollars, lately). That includes optional free web redirection, email redirection, DNS hosting, and secondary DNS. Almost all administration is automated on their website and very easy to use. I have zero complaints and nothing but compliments for them, and have been recommending them to friends for low-cost, high-quality domain registration.

From their site:

GANDI SARL is a french company created in 1999 by four persons known in the french Internet world (Pierre Beyssac, Laurent Chemla, Valentin Lacambre et David Nahmias).

Our service focuses primarily on individuals and non profit organisations. Gandi's aim is to provide to individuals domain names easily (for the technical and administratrive part) and for a price as low as possible.
