I just picked up a v1.7 at a very fair price. It is one the the older versions without individual band lights. I wanted to know if I should keep it or sell it on fleabay. Of all the things I've read the 1.7 is a very good detector with less falsing than the 1.8 versions. Is this true? I'm also concerned with this units KA sensitivity. Is Ka good enough from this detector? What would you guys do? As a side note I think I'm converted to valentine from the bel 65. The bel is in for warranty work after only 2 weeks of use! I'm not very happy with the bel at the moment.
