I have a saved search for interesting mobile Fidelity cassettes on ebay and the prices have been eye opening. Usually $100-300 (which I won't pay) but this is insane. $899 for Pink Floyd?
MFSL quality recording – LIMITED. EDITION RELEASE MFSL C-017. MY UNDERSTANDING IS THAT MFSL ONLY MADE SO MANY (HOW MANY?). IN THIS FORMAT BEFORE CHANGING TO THE VERSION OF JUST SEALING THE CASSETTE ITSELF WITHOUT THE BAG.
