I think you are underestimating the precision and skill required
to build a CD player.
I also think that if you are paying $150 for a $20 OEM cd player
you are definately getting ripped off :)
You should be able to get a cheap portable CD player for way
under $50. With a bit of shopping you should be able to pick
one up for $20.

Of course, but you will probably need hardware to handle
memory refresh cycles and such. A flash memory module
would probably be much easier to use.

A harddrive will be a much easier to use form of mass
storage, particularly if you have never interfaced
a large amount of RAM to a microcontroller before.
If you do want to use RAM, you'll probably want SRAM,
as it is easier to deal with.
