My old k40 finally bit the big one- so I'm thinking Wilson 1000, 5000, or sirio 5000. One thing I liked about the k40 was the 1/4 turn feature- made it real easy to reach up and undo when pulling in the garage. My guess is that the others won't be quite as easy. I do a 1:15 min commute twice a day, and right now am running a Cobra 25 ltd classic stock and barefoot. In the future would like to step on the 25 a little- really just looking for a unit that talks good barefoot without having to go crazy. In any event- comments on the antennas- budget is always a concern, but quality don't necessarily jibe with budget- do the others screw down like a pl259??
