This is a nice object... MakeBlock stepper motor driver ...but is seems a bit expensive. I like it because it drives 4 wire stepper motors using only two wires of the Arduino (corresponding to Direction and Step). But are there any alternatives?

2 wire + gnd stepper motor drivers

Yes and yes. You'll find the slightly cooler running DRV8825 modules on eBay too.
