Ah, yes, the wonderful ELcaset. Still miss my EL-5.
Too bad I didn't realize how historical it was when I chucked it out. Only later did I find out how bizarre it was that I got hold of mine.

To quote Wikipedia:

"…A Finnish company won the auction (by Sony international) and later sold those machines with 25 cassettes at a very low price: EL-5 + 25 cas. 795,- FIM and EL-7 + 25 cas. 1295,- FIM. It was mentioned in the ad that plain cassettes would cost normally about 1200 FIM. I think that US$ was in those days about 4,50 FIM, nowadays it's about 6 FIM. And you can believe it was a real sell-out. They sold about 2000 decks in Finland. …"
