With TI I also think that they have only a few distributors at least here in the states allowed to sell them. I remember hearing someone say that at the last great shave conference..not sure if it was Lynn and I don't want to quote anyone but that could be an issue on availability at least for that one brand..
More customs are Appearing tho...not sure if that is your thing..I know they all are almost out of my price range although they all all beautiful pieces..
