You don't say 'what thing' is expensive - just 'the driver'.  No idea what you are looking at....
But "yes you need some extra hardware to provide the current required by a stepper motor" - the pins of an mcu cannot provide enough current to drive any kind of motor.

well if can get some cheap transistors, you can use appropriate transistors to make darlington pairs and use them. I'm not sure but i believe IGBTs can also be used ( never used them like this though)
'crazy' is the new hype! =)
