HELP! I'm trying to buy my brother a portable CD Changer/MP3 Player for his car, but not the in-dash kind. I've seen so many varities out there, but I want to know what is the best. I am looking at spedning between $150 - $200. I checked out eBay and noticed the most listed brands were JVC, Sony and Alpine. Does anyone have any recommendations, brands to stay away from, brands that worked for you? THANKS SO MUCH!
