Reasonable Price For Rod Repair?

It isn't what I paid for a rod that determines what I'm willing to spend to repair it, it's what's the rod worth.  What if I got a rod for free that was only worth $50, or a free rod worth $200, entirely 2 different scenarios.  Only what I would do for a $100 rod, I would not send it anywhere, the cost of shipping both ways plus the actual repair cost and the time involved would make that prohibitive for me.  It's either finding a local, fixing it yourself, or buying a new rod.
