I don't suspect they would show up in US thrift stores either, i reckon B&O is considered luxury. It IS good hardware, no doubt, but we're rather flooded over here.
Just last saturday i scored a Rollei enlarger with El-Nikkor 50:2.8 attached to it. I had to cough up with the pricey sum of 50 danish kroner, equivalent to 8,5 usd. I also got an Olympus XA for half that price. My wallet suffered immense losses that day.
