m looking for those who deal with step motor drivers

I need some help on step motor drivers. The last one I made was by L297 and L298 but they are not good enough to work. Those of you who are working on the same field
may visit my home page. http://www.geocities.com/ugur1
Althoug its program works well I am still working on it. So I will change the driver stages I want to try SLA7052 IC but I could't have obtained it yet.
I am waiting for your advices.

I am waiting for your advices and looking for experimented step motor driver circuits.

Hi Augur,
Here is a non PBP example of a stepper controller. These are available in kit form on ebay, I have built them and can vouch that they work.
