In general, I wouldn't expect much of the no-names. Often they'll lack good coatings or have serious color-casts. Sometimes there's bargains on a good polarizer there (There's just so many sold that everything doesn't always get bid up sky-high) but in general you pay for what you get.
Sometimes there's something to be said for having a polarizer that isn't too precious to want to use if you're in lousy conditions, though: top-quality ones can get pretty darn expensive, particularly in big sizes: if I were living, say, nearer the sea or blowing sand, I'd probably have one that wasn't pristine or pricey just so I wouldn't be dissuaded from taking a chance by using my nicest. A lot of that depends what the money is to you.
It also depends on your budget and what you'll be using the thing for the most... And what size you're talking about (bigger ones tend to be much higher in price with these: it adds up to pretty significant coin, the quality difference, if you're talking about something like 67mm and up, it tends to matter less in smaller sizes.
Maybe try looking for Marumi filters, those are well-regarded and seem to be a good overall price point.
