replace hacker c-50 with what motor??

[_paralyzed_]

I have the old hacker setup with a master car controller and a c-50 maxx motor and the shaft of the motor snapped. It's $50 for parts and I can get a different motor for around $70, just not a hacker, so: WHAT IS A GOOD MOTOR FOR MY E-MAXX WITH A HACKER CONTROLLER AND TWELVE CELLS,BEST BANG FOR MY BUCK? Thanks guys!
