Valentine1 (version 2) is the dogs danglies but £600. Bel990/550 is what Ive got and is pretty damn good. If you shop around and say what prices youve already got, you should be able to get it down to about £300, possibly less. This will pick up everything apart from those damn Truvelo and SPECS cameras that dont use radar.
Dont know much about the GPS ones, but they are quite good. But quite expensive... I wouldnt bother unless you do a lot of miles around the country or have non-radar cameras in your area. Fortunately Essex is relatively devoid of non-radar cameras (so far!)
Oh, and a Laser diffuser (£270ish) is a good idea for motorway work, but make sure you turn it off when its saved you so they can get a lock on you!
