Anyone familiar with a 72mm Hoya filter?

I am looking to get a 72mm Hoya filter for my Canon 28-135 IS USM lens that I use on my Canon Rebel XT. Have you used one before, if so, what is your opinion on them? I am looking for an affordable filter, and don't want to spend over $100... this seems to be for me but want to get a users opinion of them first.

PS-- I have looked at both the standard and the Pro-1 and am leaning to the Pro-1

If 72mm is the biggest filter size you have on all your lenses then get a 72mm circular polarizer (CP).

A good quality CP (B+W MRC, Heliopan or Hoya Pro S-HMC) are usually expensive. But you can make do with just one CP and buy step up (or is it step down) rings to make them compatible with your other lenses with smaller filter size (for a you need a 72-58 mm step up ring, I think. And you can get them cheaply on ebay)

You have a lot of choices by price in the 72mm CP range. You can get Tiffen as cheap at $50 or pay a lot more than that. Since a CP cuts down 2 stops of light you want to get one which does not compromise optical quality when used. Also, ideally you need to get one that is Multicoated (MC/MRC) which further prevents any degradation in optical quality. So its not just getting B+W or Hoya or Heliopan or whatever but investing in the MC version of the filter.

In the link below you will see all choices currently available from B&H in the 72mm CP category. You should choose the one that suits you best. Any particular Hoya filter? I've used the brand, and they're good.
