Without trying to be rude, my suggestion would be to search the forums for Radar Detectors and/or V1's. I can already tell you V1 is, hands down, the most recommended one on the forum and it has been discussed at great length in different posts.
Having owned both, the Valentine and Passport, my choice is the Passort. Different strokes I suppose. I really like the multiple signal strength meters for multiple bogies as well as displaying which band each alert actually is.
RadarTest.com is a crappy biased site that charges money for radar detector test results and it is owned and operated by Craig Peterson who works for Escort and Bel and is a known hater of the Valentine One.
I have a Solo 2, cordless and small with no tell-tale cord hanging down. It works really well. V1 is supposed to be the best. However, with the increasing use of Lidar, they're becoming less and less useful.
I like my V1 very much. It's something I bought over 5 years ago, and I will upgrade it soon (about 1/2 the cost of it new.) No regrets, and I am now so accustomed to it's sensitivity and how it sounds off to different radar/laser sources that I trust it implicitly.
