Abaut the Saitek X-52. If you have the money, it's a very good investement!
I had a X-45 first, that whent well, but the X-52 works much smoother and has more control-options and a nice display for several functions. My mate has the X-52 Pro with the Saitek Flight-pedals, and that just works amazing!
But my geuss is, if you wan't to keep it low-budget, the AV8R will do just fine.
