I found GSO optics to be too variable in optical quality, hence made the decision to stop importing them some years ago. My experience has always been you get what you pay for.

Mechanical and thermal control of larger optics can make a good optic very ordinary, and get almost exponentially difficult to control as aperture increases...hence I'd be wary. The good thing about Oz is we have good consumer laws, so if it it doesn't perform as advertised, you can insist on a remedy.

Then again, if all that is advertised is that it's 1) a RC optical configuration 2) 16" aperture, these two things do not guarantee it will focus well !
