I don't know much about Cobra other than my father had one and they have a semi-big brand name.

I have seen lots of reviews comparing lots of radar detectors, most name brands... except one... Valentine. Their Valentine ONE radar/lazer detector has beaten all others in practally all catergories. It wins hands down, every time. Out of 8 reviews I've read about it the past year, it's been recomended #1...every time. I've heard from friends that know people that have them, always a good review. Personally, I'll be skipping the name brands and going with this company I've nerver heard of.

However... they are $350-400...
