i got a cobra radar detector its pretty good but same problem i catch to many interferance but that something that you will have to put up with eg. service station, taxi's i got k, ka, vg, x and a few more gets a bit annoying after a long drive but it has saved me a few times and i found that its a bit cheaper then the rest. I purchased mine when i was overseas and it was really cheap $100us so if you know someone it would be a good idea, ive also noticed them being on ebay brand new type in radar detector.
