Hi FFH, welcome to Ice In Space!
I was in the same boat as you about 4 months ago, and thanks to the great advice (or is that advise

) I got from many great people on this site I am now the proud owner of a GSO 10" dob...... and loving it.
I live up at Caloundra, there's quite a few more IIS members around Brisbane and the Sunshine Coast - if you want to see some scopes in action this very Saturday night
have a read of this thread ..... there's a gathering up here in the Coast hinterland each new moon basically, Saturday included, you'd be most welcome!
If you're interested post a reply in that thread or get in touch by pm.
Just a quick note: the scopes we refer to as "dobs" are all in fact Newtonian reflectors (which refers purely to the design of the scope optics) mounted on Dobsonian bases .... the other pic that Ving posted is still a Newtonian reflector but it is mounted on a different kind of mount, an Equatorial mount (also known as an EQ, or sometimes GEM for German Equatorial Mount).
Dob bases, as is, do not allow for tracking of objects, but they can be modified (at fair expense) to do so. EQ mounts will allow for manual tracking as is, or some come with motorised tracking (can be "fairly" easily added), but are much more expensive to buy in the first place.
Hope you find this helpful!
Steve
