OK, been out of the Ham loop for a while and before I spend the extra money for a rig capable of crossbanding (uhf/vhf) does anyone use it after the
newness wears off? Any opinions, experiences appreciated.

I used to use it when I was hiking in a remote location where I couldn't hit repeaters on 5 watts. That is to say, I set it up, but didn't really use it. Just figured it would be a way to possibly call for help if I got in a bad way.

The Kenwood D700 has some ability to control it via touch tones which makes it a little more useful, if you remember what the commands are. I kept a laminated, shrunken copy of the manual pages in my backpack. I used the 440MHz side to communicate with the HT and 144MHz side to hit the repeater. It all worked if you put everything into memory channels first and got the PL settings right.

I use it shomw when I am out in the yard or shop. Base rig (Yaesu FT-8800R) on crossband (UHF in, VHF out), with Yaesu FT-60 as the HT. NOTE: use a DCS code on the input to the crossband.

And, if any clubs have members using crossband, it is good to start a database of what members uses what input. Assign one base and one mobile frequency to each. Below is a listing of recommended frequencies from the http://www.sera.org band plan:
