yeah the HOTAS market (Hands On Throttle And Stick, aka, flight sticks) is just through the roof overpriced right now. The only thing available at a sane price is coincidentally also the best-quality entry level flight stick, viz., the VKB Gladiator NXT ($150+shipping)
you really feel the step up in quality from something like Thrustmaster. check out this guy showing off the difference in return to center
if i was a TRUE DOOM DCS-HEAD i would get the Gunfighter Modern Combat Grip which looks like some kind of angry space cobra ($484)
