      Don't think you can go wrong with a $35 Cobra. Good find!

      if you can find one the cobra 76xtr would suit your needs, I think I paid about $50 for it with an antenna. It has a little box that you can mount out of the way somewhere, and the antenna and mic plug into it. The mic has all of the cb controls on it and can easily be unscrewed from the main box so it looks like nothing is there at all.

      i have the cobra 19 dxIII, the only difference is the IV has an rf gain control. i can tell you from my experiences so far with cb's, it is a good unit if you need a compact, solid radio. not many bells and whistles, but it does a great job. it is backlit so its nice and bright at night, the knobs turn good, its compact, decent speaker, and has a quick switch to 9 and 19. rf gain will only make the audibles clearer. the only knock i have is that it will always switch back to ch 1 when you turn the power knob off. no memory. remember, the radio can only perform as well as its antenna so get a good one.

      It ends up it was the 19dxIII that Wal-Mart had. After reading some reviews I decided to pick one up today.

      Lono, what do you recommend for an antenna? Brand, length etc.

      it depends on what kind of set up you want, and hot you want to mount it. if you are going to go full mount, like on your bumper, id say go with a firestik. if you want to do a magnet mount, the best there is for that is a wilson "little willy" in my opinion. the cb radio dealer i go through gave me a ton of good info and was really honest about selling me the components that would fit my needs. i told him that i drive into san francisco a lot and i work in oakland so i couldnt get anything too high because of all the parking garages, so he sold me on the simple radioshack brand magnet mount. not too tall, and it had a spring on it so it could take a hit. i have picked up clear chatter from 14 miles away in certain areas i live and drive through with that thing. im planning on upgrading to a little willy soon though. the most important thing that you have to do is get your setup tuned with an swr meter before you use it.

      go to this website below, plenty of good info and will help you decide what will fit your needs.

      those are some pretty solid readings. what antenna are you using? its all about the antenna when it comes to minimizing your swr.

      thats about as good as you can get for your application. you can bring your swr even closer to 1.0 by aking sure there arent any kinks in your pl-259 cable, as it snakes its way back to your radio. also, try to avoid running it parallel with any existing wires and try to run the cable on the right side of your truck to keep it away from the fuel pump. it will cause interference. good luck!

      There is one other thing that can be done to help with interference noise from ignition/fuel pumps/etc. Get a piece of RG8 coax (doesn't need to be expensive brand) and take it apart. What I mean by that is cut a piece long enought to go from your batteyr to the radio. Cut the outer insulation/cover off without cutting the braided copper shielding inside. After removing the outer cover, you can "mik" the shielding off the center condutor by pushing it and gradually slipping it off. This will leave a hollow copper tube of mesh copper. Run your power and ground wires going back to the battery through the copper shielding. Ground both ends of the copper shielding. This helps shield the power wiring from outside electrical interference noise. You can also make ground straps out of this same shielding to ground body panels together. I have them run from the hood, all doors and tailgate back to the body in short strips. This bonds the whole vehicle together electrically and helps with ground plane. Sometimes the factory grounds are ok for low current but not grounded for RF purposes. Hope this might help. Good grounds are really necessary with any RF applications (RF= radio frequency energy).
