Both good mic's ,But if NC is what one is looking for and depending on the tune of the radio ? , I'd go with a Telex Road King 56 every time. (non-amplified)

RK 56 sure cures my Jeep noise.....I used a Road Devil before, too, but the RK 56 sure works good....

Not today that I know of ? but they do still have the older Turner NC's Road Kings that were amplified ,I believe they went by the RD-76's and they took a 7.5 volt battery ,I see those on Ebay all the time
