Well reading thru its specs at Optcorp - for a USD < $5K mount its reasonable.

Its carrying capacity 90lbs or 40kgs is decent. Its raw tracking ability is +/- 9 arc seconds - so better than an EQ6, but not close to a Vixen or Takahashi. Its pointing ability isn't mentioned.
Bottom line - if this mount sold for < $7K AUD it woud be reasonablly priced. $12K makes it closer to 70% over-priced IMHO.
