Firstly, you wont get a Skyquest intelliscope in Australia as they arent sold here.
The Meade lightbridge uses optics sourced from gso, they are the same optics as used in the gso dobs !
Yes The gso dob is cheaper than the lightbridge, the LB is more portable, yet the LB doesnt lend itself to fitting digital setting circles
If a 12" gso dob will fit in your car the decision is easy
