Photography is a great hobby. However, if you think that better gear will make you a better photographer, you'll be broke pretty fast. I'm a frugal person that means I hate to waste money. That doesn't mean I don't spend money on quality gear, but it does mean I won't splurge to stuff that makes a slight improvement to my photography. If you can't see the light (pun not intended), i.e. the way light hits your subject, the greatest, best, whatever camera lens and giga pixels won't matter.
I came across this article while looking for a Circular Polarizer as well. This scientific testing proofs that price is not a indication of quality.
Here's the article
If you are looking for a best Circular Polarizer (it is not a well known brand), you can find it here.
Hope you'll find the article useful if you are out buying filters. I'll get a few dollars if you buy from the link. If not, that's okay too. Happy shooting
