polarizer

im looking to buy some graduated filters and a circular polarizer to step up my landscape game. Any recommendations? Thanks

Hi I just bought a polarizer for my srt 101 and I was wondering if my light meter picks up the effects of the polarizer or if I have to compensate for it myself?

I know you get what you pay for, but I'm still new to decent photography gear and it seems silly to spend more on an ND filter than the lens. Are the cheap ones ok? What is the trade-off or flaws commonly found in cheap ND filters compared to more expensive ones? I'm also interested in replies...
