best microstepping driver (Lini/pictsep)

[student1616]

hello all,
I recently finished my stepper controller.i used reprap stepper controller(combo of l297+l298).it worked very well.
but not up to the level.the motor buzzes a lot and get hot after running for 15mins.(when i run the motor below its rated current,it ran cool but at the cost of torque).
so i came across on the internet,that running the motor at micro stepping lower the buzzing and heat generation.
so i found linistepper and picstep are the best and cheap drivers to go with.so i need some feedback from who build these controllers.
my main purpose of the building this controller is low noise and less heat generation in motor.
*my motor are rated 4v @0.95A (some thing like below post)
