I'm looking to buy a 10" dobsonian, solid tube or truss, collapsible - I'd be keen to try anything.
I was going to buy the 10" GSO dob from Andrews Communications when fellow forum member said I should try a wanted ad. The Andrews one is a 10" with 4 GSO eyepieces for $649.
If you would be interested in selling a 10" scope and you're in Sydney, I'd be keen to hear from you. I'd also consider an 8".
