Just ordered 16 radios and a new repeater for my plant. We went with the MOTOTRBO XPR 6550. These things are digital trunking units with VOIP, TXT Message capability, IP to Landline/Mobile phone etc. I'm hoping I can configure the system to reach me via radio should I fail to answer my mobile. THis will allow me to stay in the woods even longer each week! Oh yeah, they also have GPS tracking that will plot on a Google Map.
