After reading this thread, getting more curious and exploring the trucker forums, I bought a CB too, lol. I went cheap since I just plan to listen to the truckers on the road and occasionally talk. I went with the Uniden Pro510XL and a Lil' Wil antenna. It seems to work ok. Not sure it has that great of range though. The CB has been quiet lately--not alot of folks talk on there anymore. I was shocked at the silence at one truck stop, and the other had a conversation going about one guy's radio not working right, so they were testing it.
I was able to get a radio check and even talked to a driver or 2 on the road, so it seems to work fine. I have not permanently mounted mine because I don't want to drill holes in my car. Also, I'll be using it in several of my cars, so I don't want a permanent mount. I went to Radio Shack and bought a cigarette lighter adapter that has a postive and negative terminal, so I could just plug it into the 12V outlet and not run wires everywhere.
