You could also do it the old fashioned way and buy your spindle and cups on eBay. You'll find both Campagnolo and Shimano sets in French thread there right now. You just missed out on a T.A.
If you buy the Velo Orange unit, you'll have to use a crank with a JIS taper. That's okay if it doesn't bother you to put a Japanese crank on a French bike.
I have four French roadbikes, so I have some experience with this stuff.
