How much would an external hard drive for a dell inspiron mini cost?

I got the dell inspiron mini and I want the external hard drive so I can put cds on my computer music. How much does one cost?|||You can use ANY external HD. You do not need to buy the dell branded drive. Dell does not use proprietary hardware. I would think you would also need a external cd/dvd reader/writer. Again, you can use any brand. I've seen them in many sizes by many manufacturers and they could run anywhere from 39.99-249.99. If you store lots of movies and music, get a bigger one. If you are a normal user you can get a samller drive|||The sell external hard drives everywhere. Pick one.
