Cobra 75 WX ST
That's the radio I use, too, mounted under the console as Dean showed. I absolutely use it with an external speaker, though--the speaker in the mike just doesn't cut it. For now, I just lay the speaker up on the center armrest, or sometimes use the headrest to clamp it between it and the top of the seatback--haven't figured out a way to permanently mount it close to the ear yet.
