Lutron maestro or Lutron Abella. I almost exclusively use the maestro dimmers (Abella dimmmers have the same function, just in traditional toggle format). They are true multiple position dimmers, up to 10 locations I believe. As stated above, they use one master(has the led lights on it), and other locations are the slave/companion dimmers that don't have the led lights, but have all the same functions.
They have all kinds of different settings too, from countdown to adjustable fade time on lights.
