I think that there are pockets of undiscovered gems of all kinds all over the world. If you can read and write in English that gives you an advantage. Apparently razors in Europe are quite a bit cheaper and more plentiful than they are in North America and Australia. So those few that know about eBay and are proficient likely have a huge leg up in the market. There are tons coming out of Japan too. Who knew that such a tiny country would have heaps of vintage German blades, and there seems to be no end there either.
