New GPS system.

In the Uk a Bushnell radar gun is £70, and thats on ebay so in the shops/online shops it will be more expensive. The principle is all that counts in my book- a reliable way of measuring the speed. A radar gun would be more fun to use, but you need a second person to operate it remember; I am a sad loner with goldfish for friends so a GPS unit would make life much easier.
