Leaking Radiator

[JMO]

I bought a new radiator a few months back and through my own stupidity managed to puncture one of the side tanks. I brought it to a local rad place and the guy patched it up, but it's leaking again now. I have 2 options available to me right now.

1. Have the side tank repaired - I can't remember the exact cost but I think it was $70 odd.

2. Buy a new radiator.

Obviously I'd much rather save the cash and have a new tank put on it, but if it's just going to start leaking again, would I be better off just buying a new one and being more careful with it this time and possibly selling the damaged one?

I'm looking your way Blueprint
