amazon says the 20gb pack weighs 15lbs., but that's probably overshooting it a bit; i mailed a wii, an extra controller, and a copy of zelda a week or so ago, and all that weighed around 8.7lbs., less than amazon's estimate of 9lbs. so i'd say 15lbs. is kind of a highball estimate for the 20gb, maybe about right for the 60gb.
