I read through the other thread you recommended Rob and found it very interesting. I looked at the BinTel site but they don't show their 6" Dob although I was able to find it via a circular route. I Have the impression though that it is discontinued.
Andrews have a second hand Guan Sheng GS-500, complete with SV1 mount/tripod, bonus RA drive, etc. for $349. Who are Guan Sheng?
I'm still slightly bewildered by the poor reports on the Celestron. I thought they made good stuff!
A slightly different aspect. What are the care difficulties/requirements with a reflector type telescope compared to a refractor?

Hi Robert,
The dob would not require any additional mount as dob is short for dobsonian and it is actually a name for the type of mount that the telescope is on. The telescope is the same as a newtonian mounted on an equatorial mount but it is on a dobsonian mount. The dobsonian mount is cheaper and easier to use. Here is a link to Andrews' communication which show both dobsonians and equatorial mounted scopes

Guen Sheug Optical scopes are quite good value for money, with quite good optics (you'll notice that nearly every second person on these forums has a Guen Sheng telescope). I think the deal you have been offered is quite good (you can see on the above link that the current model of that scope is selling for $499 without an RA drive).
Reflectors do need collimating which becomes quite easy with practice and the right tools. There are many threads and guides on this forum regarding collimation. You do get more bang for your buck though with a reflector.
I hope this helps
Cheers
