Q-stars GPS Data logger

[e21Mark]

Just wondered if anyone else uses the Qstarz GPS data logger? I was bought one last year, for my birthday, and found it really easy to use and great for comparing lap times. In fact, despite being just over £100, it does a lot of the functions I remember seeing in way more expensive loggers when I was a gopher in Formula Opel back in the late 90's. I guess technology is just way more affordable now?

Anyway, I was just wondering if anyone else uses it and if so, do you run it alongside video footage etc?
