Yup.

Tried TIR 4 and am currently running freetrack.
The pros and cons run something like this:

Freetrack

++ Cheep (~£6 + the cost of a cheep webcam)
+ Slightly more customizable software
+ Tracks great when set up right! As good as TIR4 for me

-- You need to build a LED device
- Software profiles are a lot of hassle to get right
- Webcams use some processing power that make it unsuitable for single core machines (you can get around this by using a wii remote. Not a problem on medium-high end machines)
- Software has occasional bugs

Track IR

++ Almost plug and play, little hassle
+ Tracks great!
+ Minimal CPU usage

-- Quite expensive
- Sometimes sensitive to sunlight (TIR4, dunno about TIR5. I had this problem with freetrack to, but it was easy to fix with a stronger light filter)
