Info on Megrez II?

Considering (yet another!) telescope upgrade--looking at a semi-apo this time. The Excelsis review site lists a William Optics Megrez II 80 mm semi-apo, but none of the suppliers I've checked seem to carry it. One of the features of this scope that distinguishes it for me is it's focal length of 480 mm. With a 35 Panoptic, that would yield just shy of 5 degrees true field!!! Have any of you foks tried this f/6 80 mm? I would appreciate any comments you could make as to it's optical performance. Thanks!

I have the Megrez II 80mm APO triplet and it is very nice. It is identical except for the objective. The Doublet will be not as well corrected, but quite nice for visual astronomy.

Sorry to jump in on the thread late guys, but I just bought a used 80mm Megrez II SD and I'm interested in the apo upgrade. How would it compare to the triplet?
