Be careful. The D710 is a peice of ham equipment and is NOT type accepted for other Land Mobile services. Listening i one thing, but if you intend to transmit, be sure you have a peice of type-accepted equipment, or you will jeopardize any/all of your licenses.
Yeah, that's what I was driving at. For "listening," you can use ham gear okay (like the Kenwood D710). For transmitting, you cannot. At all.
They all make LMRS FM VHF-UHF rigs with 2.5 kHz channel spacing, but they're not "ham" rigs. They can lawfully be used on the ham bands, of course. I don't recall any with detachable front panels, though; and most have a limited number of memories (like 8 or 16 or something, but not hundreds like ham rigs often do).
