Can anyone tell me if these Circular polarizing filters are worth the cost?

Hoya make one for digital cameras but it costs $140-$170 depending where you go. I have an old linear pol filter (68mm) which I hand held in front of the 350d for a quick comparison. It did improve distant mountain clarity a little, however I lost significant colour depth in the foreground.
These Hoya filters are bit too pricy for a try it after you buy it exercise.
Any experience out there? Am I looking at the wrong filter type anyway?
I want to cut reflection from windows, and improve distant hill detail.
This photo was destined to not be any good anyways, but it illustrates bad reflection.
cheers,
Doug
