As you said, everything has its range. IMHO, any test kit that does not test for high chlorine using FAS-DPD, such as Ben's or Taylor's, isn't much better than guessing since you have no idea of combined chlorine and the dilution method decreases OTO accuracy. My advice, go ahead and get the Ps234 and don't let it consume you, if that's really possible...
