I've built my own headtracker and used it for a while...
Then I bought TrackIR 5.
Works 10 times better. Not just the HW is much better, the SW is perfect and lets you adjust very easily. It took me months to get half-used to the choppy headtracking of the DIY (I used a high-res, high fps camera and a homemade headphones clip); once I plugged in TrackIR I felt as if I had always played like that. The difference is substantial and totally worth it. Granted, I've only played E
with TrackIR, but I don't really intend on using my homemade system unless somehow TIR breaks.
There is a reason the thingy costs the money it costs, both HW and SW are top notch.
