Hi I see many topics on GCC Expert, however not much on the GCC Expert Pro-24. I am unable to afford the Puma or Jaguar at this time, but please advise what is the difference between the Pro and the Bengal. I know the GCC Expert is a stepper. However the Pro and the Bengal are Servo, however what are the differences between those two. Also, do any of you use the Expert-Pro or the Bengal?? Thanks, prompt replies are appreciated.
