Considering that you can buy the device with a discount *and* that the Logitech-people have announced they are working with ED to make G940 support even better... well I'd go for it personally.
As far as I know, there is no other stick HOTAS that provides force feedback, has dual throttles and Hall sensors to boot. It's mainly the software and especially the way it is supported by game designers that makes the stick's capabilities under-utilized. I play IL-2 and WOP and find the stick very nice and accurate in its handling. The ffb-effects in those games could be brought up to a new level though. If game designers added more effects, like the way airspeed influences the control surfaces of planes (like one can feel in FSX), it would be even better. Only time can tell if these will be supported though.
