Iso Buster/protection

Could someone please tell me which is the best version of iso buster to use with Cactus Ds 100 & 200 and also Key 2 Audio, and where I can find help, info, tutorials on how to use it as this software is new to me.
Cheers 4 now :confused:

If your hardware supports these audio-protections, I would use EAC or Feurio (or CloneCD).
