Seems they were too geared up into mass producing for Obsession telescopes and didn't want to reset a machine just for me.

I got the local product made to MY specifications and over $500 cheaper even after paying a surcharge for a custom focal length. The reputation of the mirror maker suggests it will be equal or better than the omi-torus.

Have you ever shopped for a mirror Ian?
Yes I have, I bought several over the years , mostly for other people, and I've never had a problem getting one made to spec. I've dealt with mostly with Orion UK , Nova , NPGW and Parks.
The choice of wavefront tolerances , thicknesses, substrates and coatings is a big plus too.
Never bought one from Torus though I bought other stuff from them over the years on behalf of others.
