I use the Thrustmaster Fox Pro 2 USB too. It's a nice stick. After about a year and a half it went crazy, but a quick squirt of WD40 into the pots inside the stick fixed it, and it's now been fine since (probably about 6 months). In fact, you can fix most sticks this way. Take it apart, find the variable resistors (pots), i.e. the moving part connected to the stick and spray them with electronic cleaning spray, will give you loads more life in your stick.
