Hi Tia,
Welcome to IIS,
.
The two links you quote are good. If you can, go to a reputable retailer of telescopes & see what they look like. I've added a couple of links to two retailers in Victoria for you, one of which lists a 6" dob:
http://www.astronomyalive.com.au/ref...pe-system.html
http://bintel.com.au/
Both of these stores are decent and can help you out nicely.
A 6" or 8" dobsonian will be a very good introduction to astronomy with a scope, not to mention a TOP PREZIE! Lucky man!
Mental.
