Hi Ed,
the only belgian manufactured brand that I know of is Monroe Shocks (now part of some US company collection)
http://www.tenneco-automotive.com/brands/monroe.html
Back in Europe, they are generally known as lower budget alternatives to the real deal (Bilstein, Koni).
However, this is a generic statement, I dont know how it applies to our beloved 108/109s ... even though I know they offered shocks for them.
But since the lower budget statement obviously holds for their spending on web content, you will not really find a comparison picture on the site above :p
