Alright lets be honest here, I've owned 3 different verisons of the wingman series from logitech. Each stick suffered from the centering problem... Why did I buy 3? Because they are the cheapest/best (at the time mind you) joystick avalible. Now I currently own a Saitek X45 and can not be more happy. Logitech is a good company as far as mice, speakers and keyboards are concerned but avoid their sticks. I've now sold my wingman extreme digital 3d and am currently using the wingman attack on my backup system for the good olde games
If you have the money it'd be ideal to go out and buy a CH Products stick. They produce the best joystick before going to the high end all metal cougar line from TM.
I don't think this breaks the rules as they are a hardware retailer... they have the best price for the CH hardware.
