Hi Iain,
I bought my Skywatcher Cheshire from Survey & Instrument Specialists, for around $75. (although it was about 8 years ago I think)
A shop near you, in Newcastle.
60 Belford Street,
Broadmeadow.

Sorry, mine is not for sale.
BUT
I am happy for you to come down and use mine and I can show you how best to use it. (I'm in Wyong Shire)
I also have a very precise laser collimator. [HOTECH]
(and a standard quality one for sale [Orion]).
It is interesting to compare the results. And I can explain where each one has relative advantages.
If interested, PM me for address details.
Of course this offer is open to anyone else in the neighbourhood too.
