My parents are getting me a radar dectector for Christmas but I have to tell them which one to get (my idea). They won't spend more than $150 on it. I know that won't get me one full of features but all I need is one that is good at detecting radar (k,x,ka bands). They don't use laser in my neighborhood so thats not that important. I also want one that has voice alerts and is good at ignoring false alarms. Any ideas?
