I read a review of the Aviator in PC Pilot a while back and they seemed to think it was okay, given that it is not hugely expensive.
I certainly intend to get one at some point, as the twin throttle bit is a useful notion, and I like the idea of being able to map the elevator trim to a sliding control as this is more akin to how trim works in a real aircraft (I currently do that in Condor with my Cyborg EVO joystick throttle and it works well).
