I'd definitely recommend EdTracker, it's working very well here. You only need to calibrate the magnetometer one time and then you just need to keep it still for 20s each time you plug it in to allow the Gyro to auto-calibrate (or you can click the button in the GUI to do this at any time). If you already have a Pro Micro, you just need the MPU-9150 and the software is free.
It appears as a joystick device, so you can use it directly with ArmA and other games and the GUI has settings to adjust the response and set a hotkey to re-centre but I use it via OpenTrack to allow me to tweak the axis curves more precisely and output a TrackIR signal for games.
I bought the PCB and enclosure, just to make it easier (the PCB uses both sides to reduce the overall size). http://www.edtracker.org.uk/index.php/shop
The hardest part for me was cutting some holes in the enclosure but that was mainly because I don't have many tools (and I'm pretty rubbish at cutting stuff), so had to wait until I could use my Dad's drill and files.
They've recently introduced the pre-built EdTracker Pro as well, which isn't that much different to the non-Pro but is probably the best choice if someone wants a ready-built device http://www.edtracker.org.uk/index.php/pro
