I have a few hours on the original Aerovonics version of the AV-30. It works great. Aerovonics was founded by one of the guys who started Aspen Avionics, and it shows in the quality of this unit. Solid hardware and software, and great performing AHRS.
I have been evaluating some commonly available AHRS units in dynamic maneuvering conditions for our OnSpeed project, and I wasn't impressed with most of them. They can all keep you upright, but they are not very accurate. This one does better than most.
The only negative that I can think of is that you don't get magnetic heading like on a real PFD, just GPS track (if you have it connected to a GPS).
