ITE Zeos off-axis

Anybody look through one of the Zeos off-axis Newtonians
from ITE? I've read about some of the cons of this design
(collimation, manufacturability of moderate to large
mirrors, etc.)- but the info on ITE's website seems to imply
that they've tackled these issues at least somewhat. I'm
curious because the 'test report' pdf's of the 100 and 130
mm scopes claim performance BETTER than APO ..

Well, they look neat, but are just too small for my liking. Also I would like to see someone collimate one at a site sometime. I am not certain it would be that easy. Also, I am not sure that the optics would be free of abberations with this design.
