For the last three years or so, those Class D units have been pretty standard for quality units.
I don't know about mobile units -- the biggest issue is the GPS for many of them.
At some point, I think you're spending money to power-up features that of dubious value for a mobile unit.
They now have personal Emergency Locators -- soon there will be ones with built-in text messaging that may be two way (like Spot).
In any event, if it were me, I'd get one of the ACR personal units and a mobile VHF which has a lot of battery capacity. Eventually you'll be carrying a lot of gear. In warm climes, where you aren't routinely wearing a stom jacket, that gets a bit more cumbersome :^)
