This is a how long is a piece of string question.
I spent nearly 14 months on deciding on a new scope for my wide field imaging. I looked at compound scopes from a variety of manufacturers and in the end I went with tried and tested. The FSQ106. Even at f5 it is pretty fast. It is easy to keep dew free and easy to focus with and even has a reasonable back focus. All things that I needed. It just does not have a lot of aperture which is something I would have liked.
The choice depends on budget too I suppose but tried and tested is hard to beat.
