High Sierra Topix

Has anyone used this filter? http://www.singh-ray.com/varinduo.html
I have been looking at this for a while and I think I will buy it unless I
hear any negative feedback from some one.

I haven't heard about this one before... I was always looking at getting the Vari-ND filter, but putting a polarizer on it makes it even more attractive. The price isn't very attractive but hey, I'll probably end up getting it sometime too.

Yeah the price is quite high, but I guess you pay out the nose for the best
quality like with most things.
