I think the Dobson docco on Compass has been responsible for a few Dob purchases lately.
I believe the Skywatcher uses Pyrex glass for the 10" model which reduces the cooling time in theory. However the GSO premium Dobs have a cooling fan.
I have seen criticism of the Skywatcher focusers, in that they are sloppy. In fact someone posted to this effect here earlier this year.
I have an 8" GSO and am very happy with the build of the unit. It's quite a solid piece of gear.
You've made the right choice going for a Dob, I'm sure you will be happy with whatever you pick up
Edit: My GSO came from Bintel btw.
