Thanks useful information: 
OK, time to re-gress... - to the word "Perspective" in your title.
I haven't used a polarising filter since film days. Phew! The main
reason has been - I haven't felt the need for one, and even then
it was sparing.
Now if you think that's heresy, what about this...?
I bet there are a lot of people like that.
Exegesis has been based on the following fundamental questions:
Is there a preponderance of pesky reflections that could be minimised?
Is there such a thing as universal "glare"?
Are the daily colours in life so dull as to need "enhancing"?
Does a polariser provide a saving fix for all photos?
Was Rome built in a day? (Woops!)
Don't forget the basic science:
Not all light is polarised, so the main use of a polariser to analyse
the light will be lost. It will only act as a density filter, likely unwanted
at the time. For instance, a polariser will not do much for bright reflected
bright sunlight on choppy water. It does help for other reflected
light off smoother water, cutting down on the polarised reflections to show
beneath the surface.
Anyway, good luck in your quest, and where it has been said to try for a cheaper
one first - sometimes it's useful to give vent to urges at the time - I agree.
