Xbox.com upgrade: http://www.xbox.com/en-US/hardware/hddoffer/
List price for a brand new 20gb was $80, but I'm not sure it is still in production. (Ebay prob around $40) The 60gb upgrade kit is $100, the 120gb HD is list price ... not sure between $120 -$150. The 120gb HD is on clearance at Target and Circuit City. I believe stock has been cleared at Target, but last I heard it was around $80-$90; CC has them on clearance for $75.
