I priced it all up and it was MUCH cheaper to buy the Rollcentre timers and beacons. Martin me and Sean all run the same STACK diplays and so we would have only top buy one beacon but it was still cheaper to buy 3 whole new Rollcentre kits.
Maybe I got it all wrong though
Gareth any luck with my Speed sensor? I really don't wanna buy yet ANOTHER one off Stack
