If you're getting the 24V from a line-frequency transformer, connect the motor to the transformer secondary through a triac. Trigger the triac on positive half-cycles to make the motor go forward, on negative half-cycles to make it go backward. Saves having to rectify the AC in the first place. It doesn't get much cheaper than this, should also be rather durable. The motor only gets half-cycles of power so it should be one built for a lower voltage if you need rated speed and torque from it.
