I believe other ships will easily charge you $10++ just to check the reel. If the reel has been used quite a bit, I would suggest getting a new one instead. Additional spare part costs may will make it not worthwhile.
You have to decide whether it's worth giving a shot at repairing it. If you factor in the labour, spare parts, travelling costs against its 2nd hand value it shouldn't be hard to make the decision. Not to mention the time you have to spend sending in and collecting it back.
