I have too! I'm currently running two Kenwood dual deck setups. One is in my F250 and the other is in my work vehicle. I have more money in those than I should.
I mostly use DMR now. There's 10 repeaters linked in south/central GA if anyone is interested. Its called the "Vidalia Net".
I agree the DMR through IP isn't worth a hockey when the grid is down. That's were HF shines.
