Through Amazon.fr I ordered Chronographie ou Histoire d'un siècle de Byzance (976–1077) tomes 1 et 2. They were much less expensive than the official website's retail cost (€21.96 each instead of €51 each). These are Les Belles Lettres editions, associated with Budé.
These books are beautiful! The Greek is in a very readable font and the French translation and introductory material is most helpful.
I've posted a few pictures below. If anyone has any experience with any of the books in the line, I'd like to hear all about it. I tried to get them as clear as possible with my Blackberry camera phone.
