Go and look for a Radar Detector shootout on google. I researched for a long time before I bought mine and I went with the Beltronics RX65. The RX65, the Valentine1 and the Passport 8500 (I believe thats what its called) are by far the best windshield mounted radar detectors you can get. Either way, I would go with Beltronics again any time. I paid a little over 300 for mine almost 2 years ago and it has paid itself off many times.
If you check on ebay, you can get a RX65 for around $280 including a 2 year warranty. Also, if the detector should ever be outdated, you can send it to Beltronics and they just update the SOFTWARE on it.
Remember though, if you drive like an idiot and go way over the speed limit all the time the best detector wont do you any good. If you never had one before it takes a little time to "learn" and get used to, nothing bad though.
edit: As the radarbusters website says: RX65, the best radar detector ever tested!
