I've got it and am flying it on an ASHA flight KATL-MMAA right now. Overall it's pretty good--there are still some bugs in the CDU display, lighting, and a few other things, but nothing show-stopping that I've found yet. The panel's a work of art! Systems are somewhat simpler than the LDS 767, but there's enough there to satisfy, and the FDE is yet another piece of gold from Rob Young. Seven-fives are pretty powerful for their weight, so if you want a rocketship ride, keep your pax and fuel load light and don't derate your climb.
It's brutally priced at US$57 with the bad exchange rate between pound and dollar, though.
