I've got two cobra 29 LTD classics, a navajo/realistic trc-434 base station, a midland weather max mini, and my Galaxy 959. All are awesome radios in my opinion. The 29 is a great mobile, and you can find them for about 25 bucks if you look around. I'd buy the Galaxy again if I had to, my favorite radio so far. I have it mounted from the headliner of my Bii in between the visors. No complaints and it looks great there.
Stay away from the ever so popular firestick antenna, there decent, but your better off with a whip. If you are gonna try and really run some power through your radio or a linear, I'd go with an oil cooled base for the whip. Mine is mounted on the rear passenger corner about 3in forward of the upper mount on the tire carrier.
Whatever you get, go have fun with it and use it. Go to a local lake and back up to the shore with some friends, tune your radio and you'll learn how to "skip". You can talk for miles. Personal best with the setup I have now was just after it snowed in february here in texas, received a base station up in maine, and was talking to people as far as north carolina and new york.
