As far as I know, there are just around 150 units 1 GHZ cards. I read something about Sonnet got no 800 MHz G4 processors anymore, and Freescale offered therefore some 1 GHz models for the same price. Than Sonnet equipped their last Crescendo 800MHz batch with 1 GHz prozessors. I am very sad that I didn´t take one 2 years ago for $99. But otherwise I got the 800MHz (back in 2004 for $350, ...) so there is not much loss, It´s just that my 9600 for daily usage should break that GHz - border

So I thought you maybe have a source for some of the last 1 GHz, but ok, it seems I have to wait for a 2nd hand one (Sonnet told me last year there are none left).
