Quite surprised no one has mentioned the FX 120i with version 3 autotrickler.

This thing has changed the way I reload. I can load something as little as 2 gr of Bullseye or 125 gr of BlackHorn 209 in a matter of seconds to +/- .02 (two one hundredths of a grain). Super fast and Super accurate!! Price but with the amount of reloading I do....soooo worth it!
