Well, the 2000 E/III isn't really the same as the 2000. The bodies are the same, as far as we know, but the E/III stylus (clear - no color) is a .2 X.7 mil elliptical, more compliant and has better specs. The 2000 stylus (transparent smoke color) is a ,7 mil. spherical with not-quite-as-good specs.
All of the 2000E series have decent specs, however.
EDIT: DANG! I misread the thread title and thought it said 2000 E/III. Oh well. darned eyesight, anyway!
