The Vixen GP/GPDX springs to mind.

I'm pretty sure an old G11 can manage much better than 20 seconds unguided with a 200mm lens!!
But a much cheaper option, although not as appealing, is to simply buy an Aeroquest worm for the Atlas/EQ6. It's only a little over a hundred bucks. You will get a worm that is at least 15" p-p and probably better. That's about what you'd get with an old G11. My Aeroquest worm (on my CGEM) is about 16" p-p.
However.. if your PE is that big (sounds like hundreds of arc-seconds), it might not be in the worm, but could be some non-concentric bearings or something. Ed Thomas would be in a better position to know if this is possible or not.

It seems like everyone wants the latest and greatest, cutting edge mount, many of which have teething problems or cost a fortune or weigh a ton or something else is an issue. Is there a good, reliable classical EQ mount for mainly visual use, time proven, spare parts abound, or is this just as rare as a unicorn?
How about Cave with the 1.5 inch shafts? Further up the chain would be G11, and don't forget about the Push To Astro Physics. I put hundreds of hours annually on my circa 1994 AP1200DA. Can still get service with a phone call, replacement parts in a week or so.
For grab-n-go, the Vixen SP and GP

Well, that's true to some extent. Orion doesn't make a single mount...and parts for the mounts they sell are generally available from other sources.
Please do tell identities of these sources.

+1 on the SP/GP
Yep, Vixen Super Polaris/Great Polaris/Deluxe are the workhorse mounts!

As an owner, I have had experience with the following for visual work:
- Byers or Schaeffer for heavy payloads > 40lbs
- Losmandy G8/G11 for middle-weight payloads 14-35 lbs
- Vixen Polaris for light stuff < 12 lbs.
