That's a lot of money for stuff that games just no longer use. If this was almost a decade ago when great sims were still coming out, it'd be cool but these days it's just kinda nuts. Of course, I bought Steel Battalion back in the day...
You can get pretty good joysticks that combine all the features of a full flightstick, peddles, and throttle pretty well. Sure, it's not as full featured as the bigger setup, but then you don't have to work on making your PC area accommodate all that stuff. Combine that with the TrackIR and you've probably got a really fun setup. The good thing about that is if you're playing that and decide you really want more, a decent combination joystick isn't so much money that you'll feel completely put out if you go and upgrade to a bigger setup.
