Bob,

You don't make it very clear what your needs are vs your wants. If
it's an APRS transceiver you're going for, check out this one:
http://amazon.com/dp/B00JLB94IS

No, it doesn't have DTMF or even a VFO, but it does a great job with
APRS. By itself, it can run as a tracker, or paired with a
smartphone/computer over Bluetooth it is a full KISS TNC you can use
with standard APRS applications. We've found they fit our use case for
SAR perfectly. I can nerd-out with my Bluetooth APRS app while the
normal people just use it as a black box tracker.

There are lots of other (and cheaper) Chinese handhelds with DTMF,
VFOs, memory channels, but no APRS, if that's what you need. (One
warning: I've seen the Chinese handhelds generate some poor DTMF that
not all DTMF decoders can handle.)

Is an APRS you need or a simple HT?
