Sattelite radio....it isnt like cell phone using towers. You get music everywhere. $200 is plenty to find a great model. pretty much every model thats offered for them is portable and a few are interchangable(like, you can pop em into boombox speakers and wham! you have a boombox) The big this is finding out which carrier you want. I personnaly never got sat. radio cuz i dont ant to pay 10 bux a month. I'm kosher with my cd's.
