I bought one of the 50mm versions of the same scope. They are well built, quite solid, are baffled internally and have a reasonably long dew shield. They work great as a finder guider as long as you keep all the screws nipped up tight. The Aussie dollar is high so the prices are great.
btw mine was supposed to come from china, but was sent from a Sydney warehouse in under a week.
I have one, it is well made with full metal construction and easy to focus. It works well for auto guiding, although in saying this I have switched to OAG and only use the scope for polar alignment with SharpCap polar alignment routine and it is great for that job as well.
