It could be that the limited replies is because hardly any have any experience of the beast.

Do you have the mount/observatory for it ?

 

But there have been known some issues with GSO RC scopes.

Like the focuser/tilt problem.

And this new one which I just noticed:

I don't it's rude to ask what is the purpose of your query.
Is this purely academic or just asking of GSO quality in general?
If you are not considering getting one.

Here's my opinion... you get what you pay for in RC telescopes.  

There are specific reasons for the price disparity, the main being QUALITY ASSURANCE & QUALITY CONTROL.  When you buy a serious RC from Planewave or any of the big names they have QA and QC so that the telescope doesn't leave the shop unless it's been thoroughly checked, and then they offer installation to often.  

If you look around here on CN you'll find owners of the smaller GSO RC models having various experience with maintaining collimation, which is the biggest issue for the truss design due to how they are supported on GEM mounts.  The crux often is the structure of the truss or secondary having flexure due to bad quality control so that maybe trusses are not equally matched or don't use the best quality means of attachment. 

I'll note I don't see any GSO 20" RC listed through the worlds largest vendors which begs the question "Why?"  Only on much more regional astronomy sites which may or may not be legitimate.  So beware.  

The large RC telescopes do need extra attention to detail because they are very heavy and cumbersome, so my opinion is instruments that are significantly cheaper likely have issues that may make the realistic use problematic.

i strongly agree with Paul, I have owned a RCOS 14.5" RC as well as a 17" iDK scope. These scopes are of high quality build -heavy and expensive.  A lot of cost just in the hardware and quality manufacturing.  CFF Telescopes, http://cfftelescopes...tien-500-600-mm, does make a high quality 20" and 24" RC scope - again expensive.  CFF is in Europe and probably easier shipment to India.  These large RC's tend to be 1 year to 2 year delivery times.

 

Best

I don't think CFF are taking new orders right now.
