Which version are they? If it's a first generation they have bushings with grease ports on the pivots. These are high maintenance and apparently wear out quite quickly. Later generations had cartridge bearings at the pivot points.
I had a set on my Kili Ultra when I bought it but I sold them to get my RC35s. They were nice fork though but they just didn't suit the frame (a bit like Vectors on that front).
The one thing you have to be careful with is the size of the frame. There were 3 sizes of fork all meant for different headtube sizes. If you fit them incorrectly then they don't work too well.
If you can speak French then you'll be able to understand the Fournales site: http://www.fournales.fr/
There's a set going fairly cheap, relatively speaking, here: http://uk.ebid.net/perl/auction.cgi?auc ... mo=auction
