Just found this thread, busy day and waiting for cloud to clear all night at the obs, so I was a little preoccupied.
My opinion: All this is purely budget related. If you have the budget spend up big and get the bells and whistles. If not GSO is the go.
Me and a few other guys across the planet have practically got all the bugs out of GSO gear for you guys to start buying scopes.
A 10 scope does not come with the camera centring ring on the rear plate, so you need buy the centring ring. It screws on the back of the scope.
You definitely need a focusor. A good one that allows plenty of back focus and stability is what you want. I went top of the range with the Atlas but there are other options available.
Buy a shroud and a secondary dew heater. Both those come in handy.
Easy stuff so far and you will be saving yourself heaps.
Every scope with folded optics needs collimation at some point. Marcus spent a bit of time sorting his out. Travel is going to move them a little and so you need to undertaken the task. Once collimated these scopes hold well. I have checked mine once in the last year and well you see the results I get H. That said, you need to become a collimation king to get the most out of an RC. It's not that hard but takes a little practice. A Tak scope will allow you to collimate in about 10 minutes. If you learn how to use the Tak scope really well, you don't need to do a star collimation (this takes a bit of skill)
If that all seems easy then you're up for this sort of tinkering. Personally I hate tinkering, I just want to image, so I understand your point of view H. GSO scopes are good scopes and if you buy from Bintel, they stand by the product. Feel free to ask me any further questions.
Budget with a good focusor is going to set you back about $8000 with an Atlas focusor, adapters, shroud and dew heater. Still cheaper than the other brands out there. You can make it cheaper still by using a feather touch or moonlite focusor. That will cost around $5500.
