TM-D700a
I have a TM-d700A mobile and love it. It is dual band recieve, so I can be monitoring on freq and chatting on another. It has a built-in TNC and the best out of the box APRS support of any radio. The 710a just came out so there are some deals to be had on the 700A. It also allows programming on the PC and downloading to the radio. That makes programming a breeze.
I also just picked-up a used TH-79A HT (handheld) it is a solid radio - also a dual bander.
All radios have their quirks. I like the fact that all the Kenwoods seem to have a similar interface, so if you know one you know them all.
Let me know if you have any more questions.
