Vehicle Tracker Recommendations?

I want a tracker for the R8, not sure where to begin looking. I am open to all types, but quite like the idea of a real time monitoring system which I can check on the internet.

I've got navman systems with real time tracking overlayed on to google maps on my work vans, cost about £80 for the install and £20 per month.
