Hi there
I've got a Snooper at the moment (I think it might be their bottom of the range radar/laser detector)... It works fine.
I used to have a BEL 880 that I imported from Canada which was the business until I fried it while trying to hard wire it in
If I were you, I'd go for a combination of a GPS based upgradable system, laser detector and radar detector. The only one that I know that combines all thse is the top of the range snooper.
IMHO it looks better than the Road Angel/Geoddesy/OrigineBluei as well, and provides a lot of info on it's nice dot matrix screen.
The Road Angel does have a laser detector, but where's the radar??? Police still use radar... I'm pretty sure of that.
Anyway, that's just my 2€
