joe: they proved that the phantom was a scam, it's just a black box with some non functioning electronics on the inside.
A radar detector is like a condom, the better one you get, the chances of it working is greater. The best is the Valentine one that's nearly half a grand, and next is the escort 8500 which is about $300. Anything under that is just a waste of money, those $100 radars are just for looks and coolness, the performance on those things are horrible. Trust me, it's well worth the money.
( By the way, i have a V1, escort 8500, and a cobra ) Go V1 all the way, it's saved me countless times
