Jumping in: I ordered an RT-97 programmed for GMRS. It just got here, so I haven't tested it out very thoroughly (I also just moved into a new house, so I'm still setting up *everything*). But I can confirm it works for GMRS. Plugged it in, set it up with the pre-programmed CTCSS codes into a pair of my GMRS-V1s, and had a repeater online in about 10m. I haven't even unpacked the computer that will let me reprogram the CTCSS codes - I spent more time trying to figure out what codes they'd put in than anything else.
More when I have more time to put it through its paces.
