If not a scam, perhaps try to hand out even a single copy of the driver to a reputable forum member for review?
That's exactly what I was thinking! There's absolutely noone who reported that this is working or that this even exists. Who knows what you're really downloading after paying some hundred bucks.
As already said, if this would be real, everyone would be aware, if it's too good to be true, stop dreaming about it!;)
