I,m in the process of sourcing all the bits together for one of these DSC for my 10" GS Dob.
Encoders from US Digital = $150(Aus) + shipping
Mounting Kit = approx $90(Aus) (Bintel are actually the most expensive @ $100)
Interface = ? Depends on which way you go. Check
THIS THREAD for price on the components.
I,m getting a fellow Iceinspacer to make the interface for me. Then you need a Palm or Laptop or such to connect to the interface.
So you would still be looking at a few hundred $ all up.
If anyone knows where I can get the mounting Kit and encoders cheaper please let me know.
