It does depend on the current draw of the Motor.
The TB6612 ( board sold by Pololu) is inexpensive and works well with small motors. It is a Dual H-bridge for two motors.

What about the other H-bridge chip Pololu sells:

Many seem to be cheap.

The L293d costs $4.12 on digikey. The SN754410 is pin compatible and costs $2.33 and it can provide more current.
