Honestly, it is just perfect - and free. Get yourself the PS3 EyeCam and play a little with the configs.
For me, Facetracknoir 1.5 works best.
You could also try my DCS BS config I found earlier in the Forums.
Personally, I think that paying 150 € for the electronic waste of TrackIR is not worth - maybe it works better but it also costs about 150 times more
