Thanks Bojan,
Now its much more clearer. Adding encoders and EK's box to interface encoders makes it more efficient 'cos encoders can't slip but stepper motors can.
Adding stepper motors to Bintel Dob is bigger project than just adding encoders and EK's box.
You are right that I will want GoTo later on, but for now I would be happy with EK's box. It will come handy anyway if I decide to upgrade to GoTo.
Its a bit strange that EK didn't want to make it business and sell it as a self building kit. Like the ones you can get from Dick Smith or Jaycar. This way you buy parts yourself, buy (or make your own) board and chip from FAR Circuits. It would be nice if I could buy all the parts from one place
Thanks again

Geoff,
Thats the best option. Either way I need EK box first.
I found PIC16F84 on Jaycar website but not sure if its the same though. There are couple of different ones and then they need to be programed. Its much cheaper to get a board and chip from FAR Circuit.
cheers
