For those that are interested I've just ordered a V3 handset from a UK supplier called Opticstar (see link)
http://www.opticstar.com/Run/Astrono...=0_10_5_2_0_35
The handset and cable can be purchased from them for around $194 pounds which converts to around $340 aussie dollars at the current rate. They can be emailed at
info@opticstar.com for details and payment options. Can't use their website for payment as it's for UK resident only.
I only did this after speaking to Andrews who couldn't say with any commitment when (or if) they are getting the handsets in and with a price thought to be around $400-$450.
$340 delivered and insured from the UK seems a better deal. All I hope now is that it actually works
Will let you know the result in about two weeks when it arrives
Cheers
Grant
