This system by robitronic seems to have the same basic priciple as the iLaps system.

Are any clubs using this system?
219 Euro's for the basic system - decoder, bridge sensors and 3 PT's
29 Euro's per additional PT.
All plus postage/delivery.
Seems very similar to the i laps system, and looks quite well packaged.
