external hard drives (for music mostly)

[bustedchucks]

im running out of space and need to get an external hard drive. ive been looking at maxtor and iomega 320 gb models. like $100 from amazon and best buy and such.
Better place to buy from?

Im going to use it almost entirely for music, does this give any special considerations?

will dl'd music be difficult to send to the external hard drive, keep in my that im a dummy. and will i need to do anything special to get it to my windows media player library?

thanks for any help, general guidelines or specific suggestions.
