I have purchased dozens of Circular polarizing screens over the years, as different lenses often take different sized screens. I've found no difference in the performance of one brand over another, although I shy away from those offered at dirt-cheap prices.
I agree about staying away from "dirt-cheap" polarizers. Some years ago I had the best image I captured all season (fall color in the Idaho Rockies) ruined by an inexpensive polarizer, not a dirt cheap one but one in the lower half of the price spectrum and not made by one of the brands we are talking about. I would have paid a lot to have that image as it should have been and learned my lesson. I know some disgree but my advice is to stick with top of the line versions, even in the top quality brands we have discussed.
