Hi BobYU
There are a number of shops in the Brisvegas and Gold Coast area. It would pay to check out their websites to get an idea of their prices. There is
Yorkoptical in the Valley,
Sirius Optics at Rochdale (?) and
Star Optics on the Gold Coast.
The most competative prices though usually (but not always) gets split between
Bintel,
Andews Communication and
MyAstroshop (again check their websites). Even with postage these three usually come out on top.
If your not sure what you want come up to Cambroon near Kenilworth next dark of the Moon. There will be a few of us there with a number of different types of scopes in all shapes and sizes to try out.
At the price your looking at though, I would say that a GS 10" Dob and a couple of good quality eyepieces from Andrews will get you up and going.
