Hi Jono,
Have you had a look at
www.Andrewscom.com.au? You can pick up a very nice GSO 8" dob for only $399, or a 6" newt on an EQ mount for $499. The dob would be easier to cart around in the car.
Quite a few of our members have bought from Andrews, and I don't think I've heard any complaints, only praise.
Hope this helps.
