An excellent post Joe ! Your are right. The most economical full featured controller is still the Sandevices. The 4 output e6804 is only $69 for a very simple kit, and it has as much capacity as the E682 (7 universes multicast or 12 universes unicast), but limited to using only 4 outputs. Anyone can learn to place a few components and solder them, so there's a lot of cash to be saved with Sandevices.
