Is there any differences between the 3 besides nxdn and the heads? I want to get one for my car and I'm wondering if I could save some money by getting an older/used model. My area is standard VHF/UHF for fire/EMS and UHF P25 for some LEO (others are VHF) and CHP (whatever new toys they have). I don't plan on doing programming in the field so extra buttons don't really matter to me.
It also may have to live next to mobile dual band HAM radio too at some point.
