There are a lotta diif kinds depends what you are looking for. The Harmon Kardon ones are pretty good. So is JBL, Creative Lab, Infinity ones(same price range). If you want better sound quality in that category you can go wih Bose(better sound in small console). If you want better than that you can go Bose Wave music with a docking station for IPOD. Or you can just buy a headphone---> AV spliter and just connect it to your stereo or TV(get monster ones for better sound quality). If you are looking for used. Cross check prices in Craigslist and Ebay. There sure are a lotta used ones out there too. Good luck !!
