I have been pondering over the trackir 5 for a while now, I built my own headtracker and used the freetrack software, but its been hit and miss buggy, been using freetrack for a while with flight sims ect. But like i said was buggy could work great for a hour or 2 then it would go daft or just stop working. Anyway i bought the trackir 5 with pro-clip from www.[B]flightstore[/B].co.uk only 10mins drive from me
And i must say works like a charm with pro clip or hat-clip both for elite and my flight sims. Pro-clip is great for when i need too put the headphones on and the cap-clip is good when using normal audio, i would highly recomend. By the way i think flightstore are the cheapest in the u.k even on e-bay a 2nd hand 1 will set you back in the region of about £125 with pro clip. There as been a cheaper version from china at about £75 on ebay but i wouldn't take the gamble.
