How do I choose a circular polarizing filter, and will a cheaper one still reduce glare?

I was advised to use a polarizing filter to reduce reflections on shiny glazed ceramic objects. I see a big price range between 52mm circular polarizers, from budget options to much more expensive branded filters.
What differences matter when choosing a polarizer? Will a cheaper circular polarizer still help cut glare, or are the more expensive ones noticeably better? I’m mainly interested in reducing reflections, not special effects.

Here's polarizers' test: http://www.lenstip.com/115.4-article-Polarizing_filters_test_Results_and_summary.html. Even if you don't choose anything among these filters, it still gives good idea what to value.

For an SLR/DSLR, buy a circular polarizing filter (CPL) in the correct thread size for your lens.
Yes, even a cheaper CPL should reduce glare/reflections. The main differences between cheap and expensive polarizers are usually:
- optical quality
- light transmission (better filters may lose less light)
- coatings, which help reduce flare/glare from bright light sources
- durability/build quality
So if your main goal is simply cutting reflections on a shiny subject, a budget CPL can still do the job. The pricier filters tend to perform better in demanding conditions, especially when strong light sources are in the frame, and may have better coatings and overall image quality.
In short: get a circular polarizer that fits your lens. If you’re a hobbyist and shooting controlled subjects, a less expensive CPL is often sufficient. If you want the best image quality and better resistance to flare, spend more on a higher-quality multi-coated CPL.
