Hi winesky,
I havent found major differences between saxon and skywatcher dobs. The bintel dobsonians have a dual focuser which is nice.

I would if you are going to spend $400, try to get an 8inch dob instead. Alot of objects will become brighter and accessible with not a huge weight gain for the scope.
