Well, of course you'll be fine with the Fighterstick. Everyone would be, if they could afford one.

It's an awesome stick, the best I've ever had. And yeah, it is built like a rock, and if you do manage to break it somehow, CH also sells replacement parts. It will serve you well, that's for sure, and if you'll ever want to upgrade to a full HOTAS, then you can build an excellent one around the Fighterstick (CH Pro Throttle + CH Pedals FTW

).
Though HT is right about the rudder, unless you don't mind lack of roll control (or keyboard-based one). In FS, it's not that essential, but in flight sims, rudder is really nice to have. Though I must say, last time I used a twist handle with a flightsim, I nearly broke my wrist when trying to make a coordinated turn. With pedals, it's very intuitive, and feels like a real plane. They're also good for most racing games (as long as the clutch isn't required) and driving around in FPSes. It's not 100% necessary to have pedals for FS, but they're worth buying.
Also keep in mind CH stick have no force feedback.
