It's interesting that old audio equipment is making a revival. Tape decks have become the norm for new stereo equipment for a while now. I have never been convinced by cassette quality, we bought them because they were cheaper than CDs and more convenient. I thought audiobooks on cassette sounded clearer and crispier than cassette album's. Walkmans drained batteries very quickly.
Reel to reel used to get jammed from memory. I know there is a very niche market for the RCA videodisc but they stylus for the players and no longer manufactured. There is a market I Laserdiscs which surprises me but I guess people want original cuts of Star Wars.
