Hi Dan - I realize that most of the people posting here are sophisticated enough to know this stuff, and make a decision based on their own needs (or psychology) - but I often like to play the Devil's Advocate for newbies who are reading Audiogon and wondering if they now need to spend $250 on a scale for their $650 Rega, etc. These pocket scales (like the $35 American Weigh type) that are used in the jewelery trade are very accurate - they have to be. A tenth of a carat can be $100's of dollars.
BTW - in my own experience, subtle changes in antiskate have a larger effect on sonics than equally subtle changes in VTF. Everyone's different, but I need about two tenths of a gram change in VTF to hear a really significant change, while less than a 1/10 gm. change in A.S. can make a huge difference to me. So part of my reasoning also, is that I don't think I need a scale which is maybe 20 times more sensitive than my ears.
