ClearAperture, Off Axiis Objective, Newtonians.

I hope this discussion has not already been here, if so humor me. Here
in the US, from Orion, a newtonian telescope is being sold, a 91mm clear
aperture newtonion reflector. For about $900.00 right now. My question is,
are any of you familiar with it? Is anyone else making them? Perhaps larger
ones? This seems to be a very good innovation. Can amnone comment on this?
The claim is that they are as good as apo's which would sell for much more,
due to the lack of chromatic abberration, since the off-axis mirror points
the light off to the side, eliminating the need for the secondary mirror. If
this is really so much better will we soon be seeing larger apertures made
this way? Thank you. Sincerely, Bill.
