In my experience, the weights are all over, from nice and light, to boat anchors. I currently have 4 70's Fenders, and they vary between just under, to just over 9 lbs. The '78 Precision I had was 8 lbs 9 oz. 2 of mine have been played to death, and two have been looked after very well, they're all nice basses to play, and they sound great, though different from each other.
The condition of this one above is lovely, and I particularly like a black Jazz, they do look fab. The gap in the neck pocket is a shame, but if it plays ok, that wouldn't put me off, but the weight is the killer for me, my shoulder hurts just looking at it.
