There may be new base staion radios being mae - but I'm not aware of who makes them.
I use a nice mobile radio and a 12v power supply, antenna, and coax. Works for me - very well I might add. I would get a Cobra 148GTL or a nice new Galaxy mobile radio - either one would be more than adequate. Total cost (antenna, coax, radio, power supply) should be around ~$300 as suggested. You can do it for cheaper - depending on what you choose!
