The Skywatcher focuser itself is OK for loads up to about 1kg, but a new focuser (eg a moonlite) would be a good idea if you are wanting to use heavy cameras.
if you do get a CF scope, be prepared for dew - I wrapped mine in Al tape to reduce the sky cooling (worked well) and you will need a fan to keep up some airflow in the OTA.

I'm really sorry, but I'm finding your post bit confusing, Shiraz.
I Googled "CF scope", but can't figure out what that is. (Edit: Ahh! Carbon Fibre!)
And "Al tape" - is that aluminium foil that is used like a space blanket?
I'm uncertain which way to jump. I'm still toying with the idea of lashing out on an Espirit 100 ED, but for that sort of money I could afford the f/4 200mm Newt, plus a coma corrector and a remote focuser and heavy-duty focus rack (yes I'll be dangling a DSLR off it).
