Just happened to find this link on the Georgia State Patrol website: http://www.theiacp.org/profassist/RadarCPL.pdf
It lists all of the International Association of Chiefs of Police certified radar guns for this year. It includes the manufacturers, models, bands and features of each unit. Not sure if this is old news or not, but just thought the forum might like to see it.
Edit: Found the lidar link also: http://www.theiacp.org/profassist/lidarcpl.pdf
