Hey Saud.
I just purchased:
Flight Simulater X (£20 off ebay)
Cheap headset (£5)
Saitek X45 joystick and throttle (£80 -£150 off ebay)
I connected it straight to the internet using gamespy which is on the mulitplayer option of the game.
If you are looking for good simulator training in your own home this is perfect - FSX has really helped me to become a better pilot (in real life!).
Yesterday I joined a game in Gran Canaria, I was talking to ATC and everything - I sort of forgot I was at home a one point - it really is that life like.
There are two helicoptors to choose from on FSX as well as over 20 different prop's and jets.
Hope this helps you. Holla if you need anymore info.
