Get a used laptop computer (40-80Gigs hard drive-good sound card)($400-500), a cd brner ($200) and a decent DAC ($300or so)and you can store hundreds of cds. No moving parts to wear out. This will give you non-compressed ,great quality sound. Recommend that you some research in this area. You can always upgrade the DAC later--say an Apogee mini-dac.
