Hi justme,
to IIS!
A six inch dob is a perfectly fine instrument. It also will be much better constructed and easier to use than smaller scopes set onto an equatorial mount. It is a good scope to get that isn't too expensive, and will perform admirably, and won't hurt too much if the interest in astronomy doesn't progress too far. It will inturn still be a good instrument for many years of service. And your reasoning about a larger scope is very sound. I won't dissuade you from getting a 6". Good idea,
.
A Saxon scope is just fine. This company doesn't actually produce telescopes, but sources them & has its badge put onto it. The scope would have originated most likely from Guan Sheng Optical (GSO) in Taiwan, or from the Skywatcher parent company, Synta, in China. The quality difference today between these two sources of dobs is very marginal. You wouldn't have any trouble with these.
I can recommend two astro retailers who stock the GSO range of dobsonians, Andrews Communications in NSW, & The Binocular & Telescope Shop, Bintel for short, in NSW & Vic.

Have a talk to them about pricing, & freight if you need to.
I guess I should also ask where you are as there are also several other very good and equally competent astro retailers whose ads appear on the right margin of this page, with whom I've delt with too.
