One word of warning, I purchased a while back a Hoya Pro1 CPL from HVStar for £30 + shipping, adding more items to my cart just doubled, trippled the shipping etc etc.. so that was a joke especially being as the item I was adding was a hotshoe bubble level, something that wouldnt have effected the package weight very much, I send off lots of items worldwide & work with eccommerce software, their cart system shouldnt double the prices, maybe they have fixed it now, I dont know.
The main problem was the actual filter, it was VERY poor indeed, it flared up in the worst way possible, there was no way it was a "genuine" Hoya, despite them saying it was, but I guess common sense should have told me that it cant be that good for £30, when the same thing from a reputable online store in the UK is £130!!
But lots of people say they have good experiences of HVStar, but I thought you should hear both sides too
