Forget a rabbit hole, that site is a whole warren!
Even after half an hour clicking through models I've not found the red Aiwa tape with AM/FM radio model I had as my first "walkman" or the much cooler, powered by a single AA battery Sony model with a silver plastic case that I used to dull out the bus to college in '92-94.
They both vanished in house/country moves as I've travelled around, but I'm regretting getting rid of them every time I get that itch but realise there is no good reason to buy a casette player on one of the second hand sites (except for nostalgia).
See also my longing for a minidisk player, inspired by several folks from around here
