Hoya v Hoya Pro1 CPL filters

[binliner]

I'm looking for a Hoya 67mm CPL but warehouse express list 4 different ones without any info to differentiate between them.

Can anyone explain the basic difference between the ranges?

I want to get a good one but also don't want to spend a fortune if it isn't necessary so any recommendations for a cheapish but good CPL would also be appreciated ;)
