I've never owned an MP3 or any such music holding device. I have always burned CD's and played them. I would like to start using one this summer on the boat. I have a bunch of CD's to download onto it and want to download some of the current music that I would never buy the whole CD of. I have a power supply and port on the stereo for a player to plug into. Is the Ipod the only real choice? I want easy to use and easy to download to. I really don't have a price in mind. I imagione it will cost around $400?
