I just bought 2 Lacie 500 gig external hard drives from Best Buy for $99.00 each plus tax. My money would be to go to Best Buy or look at their website and see what they have available and the prices. I just did no more Lacies but they do have Hitachi 500 GB for $125.99
happy shopping!
Here it is for you.

Those smaller drives are great for data but not for music because the music eats up too much space to quick, I have over 5,000 songs on one of the units I just bought and it didn't even put a dent in it.
