I believe the GS 100 is no longer made; An "Alivio" FC-MC20 triple 22/32/42 shouldn't cost more than $50.00.
A "Sora" FC3303 triple Road crank 30/42/52 shouldn't be over $70.00.
These are Shimano cranks. Don't forget to add labor to these prices.
Whether it is worth the repair depends on how much you like this bike. Is it your favorite, or does it sit around most of the time? You have to make that decision.
