I have used MS wireless keyboards and mice for several years now with no problems at all.
Have used wireless keyboards and mice - but have hoped someone could answer this: is there a decent wireless joystick that you can use to fly off of a big flat screen TV?

I use a Saitek Cyborg Evo 2.4GHz RF Wireless stick and am very happy with it. The battery lasts long enough and gives plenty of warning via a flashing red light when it's running out. The only thing that I've noticed is if you don't move it for a certain time it goes to sleep, but I just pull the trigger (brakes) before manoeuvring again and it wakes up.
Thanks Nick. One of my current controllers is the 'wired' CyborgX. Overall, its build quality seems SLIGHTLY better than most for that price bracket. However, its throttle are now faulty. Do you know if the 'pots' are replaceable? I guess they'll be the same ones as yours.
