Aiwa auto reverse.......

Hi,
I hope this is the right group for my query.
I work in a military museum and in a display on WWI we have sound effects of
gunfire and shells exploding, etc. These are on tape and play on an Aiwa
portable cd/cassette player. The model escapes me for the minute, but it's a
pretty good one.
As the tape plays constantly for seven hours a day, seven days a week, the
auto-reverse facility (understandably) has given up the ghost.
My question is, would it be worth repairing? I know even for an engineer to
look at it will cost, so should we just invest in another one?
Many thanks for any replies.
Tony.
