I'm ready to place an order from AO for an M1G... I see they have a ELK-128301I (insteon kit) that listed as the M1GSYS4S kit plus the serial expander and insteon powerlinc... Looks like almost too good of a deal since the powerlinc and serial expander (I think it is the M1XSP which also gives me thermostat control?) are $150 if purchased separately... but this kit is only $5 more than the SYS4Skit. Just doing a sanity check to make sure I am not missing something. Also, I see in the photos of the KP2 panel on the AO site, it has gray surrounding the display, and some photos it is white surround. I am ordering another KP2 and want to make sure they are both the same (prefer the all-white). Any insights?
