I would agree on pre recorded tapes quality.
A while back I bought up some " old stock" tapes from a dealer, about 400 I think.
Of that 400 I threw maybe 100 away as even though still sealed the rollers had frozen or tapes deteriorated.
Of the 300 left, probably 200 were just ok in quality.
Of the 100 left maybe 75 were very good with about 25 being spectacular.
So yes not very good odds really.. lol.
