The problem with emitter followers is that not that I'm going to use N channel MOSFETs, I'd have to build my own charge-pump. I would also have to use a small pull-down resistor to keep gate current up - This would waste a lot when it is powered if that makes sense.
I have found out about the IR2104. I found this out from a company which sells thousands of stepper motor drivers to both DIY CNC machine creators as well as large CNC-based companies. It seems like it will meet all of my requirements, but it does cost about £2.50 per IC.
