My 15" macbook pro is out of warranty and my charger stopped functioning anymore, and it was confirmed that it is the charger that is broken. I went to Machines and they said that the repair would cost the same as buying a new one which is at RM319 in which that i can't afford that. So my options are

-buy a second hand/cheaper charger which i have no idea where to find

-repair the charger, but i also don't know where to send it to because it's Mac.

so if you guys could offer me tips or any help it would be appreciated, thanks.
