vexta stepper/driver

Hi all,
Going through the old posts here, I noticed that a few members are using the vexta 5-phase steppers/drivers. I have my eyes on a set of Super Vexta drivers and vexta PH599H-A steppers that are going cheep. Could you guide me on their performance and which software are you using to drive them. These are 0.72 degrees and 2.4A Nema 32 motors. I couldn't find the specs of the motors on the web. Oriental motors web site doesn't seem to have these numbers. Is there any other place should I look in.

Regards,
Zafar
