microstep

Dear All,

I'm looking for microstep drivers for step motors. I found Alan's Picstep driver and embeddedtronics driver but i'm not happy with expensive LMD's. I'm looking an open source step driver which is capable to prevent mid level stepping resonance, does not use LMD18245 (mosfet is highly prefarable) and 45-50V 3A.
Can anybody help? Thanks in advance!
