The Gakken toy record cutter was only 8000 yen when it was released[0].

My spouse bought one on a whim. The quality is ... quite bad. It's a tool for learning about how this works though! So it was a fun little activity. But it really is "just" what it is.

Maybe Teenage Engineering's toy that looks like is exactly the same tech is better. I have my doubts.
