I have never seen one that was actually for sale in the here and now. I have seen listings that "ended" months or years before I found them. I have to think, though, that one could find it for less than 5-figures. I would shop in Tokyo or Hong Kong. Contact someone at Hifido in Japan, and let them know you're a serious buyer. And then settle down to wait. OR, jump on the one you've found. On this subject too, it would be wise to contact JP and ask for his input on cost. He has a website, Fidelis Analog.
