Here's a nice little article with some S2G stuff in it. The Sharp QT-27E made best portable 1985! https://www.whathifi.com/features/crt-to-vhs-tech-got-left-behind
Interesting article. Since value for money is one factor the QR27E isn't such a strange choice. I disagree with the authors definition of portability. Try doing Music and Movement with a class full of kids (something my Mother did for years using a Sony CFS210) using just a Smartphone.
