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. Also, Skywatcher used water soluble flat black paint inside the OTA and it ran all over the place when it dewed up - recoating with blackboard paint fixed it.
