Was the PM 1 a short lived model and if so why was it discontinued?

I think there's no market for non-goto mounts anymore, particularly expensive ones.
IMO the PM-1 is a downgrade from the Space Boy and P2Z because it lacks setting circles. Having a non-goto mount with no setting circles seems a bit backward.

I sold my PM-1 a few years ago. It was a fine mount. I took it with me to the US for the 2017 total eclipse. It worked just fine. I sold it because its payload is a bit too low for my new 500mm lens.
In my 30 years of using eq mounts, goto or not, I have never used the settle circles. I do agree that it is too expensive in today's standard.

I think Orly is right.
I really like my PM-1 but a goto version that can be auto guided would be nice. That being said it's a very simple and very accurate mount, just like the P2-Z. I never used setting circles either so that is a non issue for me.

I'm a fan of setting circles. I mostly use the Dec circle and sweep up what I'm looking for in RA. I didn't realize the PM 1 did not have them. I think the light weight Vixen AP is a really nice small EQ but no setting circles. Observing these days in light polluted urban skies I think setting circles are a must if you don't have goto

Well, I use the Astrotrac to observe from home, and I live in the awfully light-pollution washed main plain of northern Italy.
Since those mounts can handle only small telescopes (the heavies thing I managed to use on the Astrotrac is a C8, and guess would be the same with the AP), and those telescopes have all reasonably large fields, finding stuff is much less hard than actually seeing it.
However I think that setting circles could have been useful for astrophotography, especially if want to aim the camera not to an object but at a specific point in the sky, and do this repeatably

My problem was that, it's very hard to see an object in the camera viewfinder (or live view), so even if you can find something in the eyepiece of a telescope, it's much harder to frame it properly with a camera..
