Hi mate,
I am looking at upgrading to a 16inch LightBridge but my wife says I will have to sell my current scope to fund it. You might be interested in it. It's not a Dob though.
Skywatcher Explorer 250PX EQ6. It's the exact model as listed below. Comes with eyepieces. Will talk to you in more detail if interested.

Interested in $1600.
I also live in Melbourne so that will make things easier.
Cheers
Peter
