The standard A4988 stepper motor driver from Pololu is an excellent design, and is hugely popular in the DIY community (especially in 3D printers). Pololu saw that they could improve on the standard design by making it exactly the same, but on a better circuit board that dissipates the heat better, so you can have more power out of exactly the same electronics.
