I am a musician looking to inject some spice into my music life and thought maybe It could be fun to use some Minidisc for playing backing tracks but I don't know anything so here are some questions:
1: whats the oldest year/model that would be safe and reliable to use?
2: is there any older models that are unreliable, any specific brand/model to avoid or to watch out for?
3: where are some good places to look and price ranges I should be aware of?
4: is it possible to repair broken ones?
