Had a galaxy 66
My Galaxy 66 was a great talking radio. Then I switched trucks and was too lazy to put in good coax and a good antenna. (I moved into a new Pete 387, the fiberglass T2000 lookalike, which came from the factory with a cheap radio, thin coax and cheap antenna). The radio still worked ok, but not up to its full potential. (I did get the SWR set, I'm not that lazy). At any rate, a couple weeks ago, got caught in an ice storm, and either broke an antenna wire or bent the mount. Didn't catch it soon enough, but when I finally figured out my radio wasn't quite right, I had fried it (bad short in the system, the coax was grounded center pin to external shield).
Haven't had time to stop at a good CB shop yet (there are none that I'm aware of in SD). When I do, I will see if they can do anything with the Galaxy. If not, I've heard the DeltaForce Magnum radios and they sound great, and I thought I'd give one a try. Both the Gal 66 and the Magnum are around $300 new, and after frying mine, I would be leary of buying a used one unless you actually got to talk on it and have a trusted friend tell you how it sounds.
As far as good coax and antenna, what the others have said is true. If you are going the cheap route, it is best to buy a cheap radio and quality coax and antenna. YOu can always upgrade your radio if you want to, rather than being in my boat and having to do all three.
