Blasphemer!!! No radar detector is worth more than a knife!!! You should hang your head in shame for even suggest it.
obviously ya dont drive like i do lol, my detector has saved me enough money to buy several custom folders believe you me, & thats not even considering insurance costs, i drive a 'vette FWIW.
the very best detector is a valentine, imho one of the main pros is the Ti case vs platic on most others, which breaks/cracks up, the sensitivity without lots of falses, and the directional arrows, also they offer upgrades on old units, only con is the price ~$450, i got a used one for $150 & liked it enough to buy another new one from valentine. i have heard the batt operated escort arent very good, but i haent checked out the new reviews in a yr or so, they might have improved, i do know some Bels are ok too but are near the V1 price.
