$130 posted in Aus.
Good condition and in full working order. Firmware updated a while back by the immensely helpful Serge @ Astrodevices.
Includes original cables and mounting plates. Manuals can be downloaded from the website.
I'll chuck in the cable for the Orion Intelliscope handset Serge made for me.
Cheers
