I am an avid Classic Rock and Country Music collector.  My computer has over 8 GB of Music files, but I still enjoy buying used vinyl for the original recorded sound. I have had much success bidding and buying used CD's, Vinyl, and even video games on Ebay. I use an Insignia Pilot Mp3 player (also purchased on Ebay), but want to warn you about Mp3 players and Ipods. If the item is listed as "for parts" or dosen't work" skip those and focus bidding on the players with guarantee to be in working order. Some times players not working can be repaired, but the cost and time spent repairing them are higher than just buying another player. Also if the player you are bidding on has a link for "Square Trade Warranty", that is a good option to use. This company will warranty electronics and appliances purchased on Ebay or new in the store if within 30 days of purchase date. RocK-On
