Been a while since ive been on the site so i figured i would mark my return with a new thread. the title says it all. I vote the saitek X45 flight stick/throttle.
I'd say Gravis Destroyer Xtreme. Very simple but nice to use.
Recently at PC World i bought Flight Sim 04 and Nero 6 for £50 for the both of them. Seeing as they would normally cost £105 to buy i thought i would seize the oppotunity and get them. Some of the Aircraft you can download for Flight Sim 04 are great. Even have interior seating in the commercial stuff.
I'd choose the saitek x45 just becuase you get 16x3 programmable buttons. Very useful in flighsim 02/04 and in games such as Lock-On: Modern Air Combat.
