Uses webcam vs the head thingy.

Anyone try, anyone know if it's decent or crap?

i'm using it for arma1 with selfmade hardware (like in the howtos).

it worked very fine :)

not tested yet for arma2 but i heard that the new trackir interface uses an encrypted interface :/

There's an moderator poll about it's support

If you search for "freetrack" in forum titles and filter ArmA2, you'll find it's a pretty common topic.
