Looking to buy a new rader detector - needs to be the dog's b*llox and be compatible with all cameras/guns etc. However I don't want buy one for it to be useless in 6 months if a new camera is released! Whats the Snooper S4 like?

I've heard good things and it's meant to be better than the Roadangel? All comments appreciated :D
