I have Soudet equipment and it is quite nice.
Soudet is not the most advanced when it comes to e-commerce. My wife goes to France on business frequently so we have the advantage of being able to conduct business face-to-face.
However, the person to speak to is Bruno Royer. A very nice fellow, and he is fluent in English. His e-mail is (or at least used to be):
soudet1@club-internet.fr
Most of my correspondence with him was via FAX. His FAX number, as dialed from the US is:
011 33 1 43 143 311.
Since they are also the Prieur distributor, you may be able to contact them through the Prieur site (which has been up and down over the years):
http://www.prieur-sports.com
Try these methods. You could also call directly which could be pricey depending on where you are:
011 33 1 43 14 33 15
