As it turns out they are all digital anyway (didn't look at the specs until
you said what you wanted, sorry).... However, if it helps any, I live in an
RV and was in Columbia SC while I went to USC) and used an LG-4400 at the
time, (it worked great).. I still have the 4400 (tri-mode, I need analog
outside ((not in)) Vegas now), but my sister had looked at, and actually now
has both the LG-4600 AND the LG-4500 (shared lines, one has a speakerphone
and one doesn't, one for her one for her daughter). Both work great, and
they love the voice dialing (but the 4500 does voice digit dialing also ((ie
say the numbers to dial)). Turns out the weight difference is minor, but the
4500 is a tad heavier. Don't know your age, but her mom/my sister is bit
older and can't push the buttons so well and loves the voice dial and
speakerphone (of the 4500), while my neice loves the lighter weight, and the
cool EL look of the 4600. She made a deal with the CS, and instead of
getting two 4500's or two 4600's (second free) she bought a 4500 and got a
4600 free. Do you need/want the camera part of the audiovox? Sound wasn't
quite as good, and it was heavier/less battery life/sound was not quite so
good ((and it costs a lot to xfer pictures)), but maybe if you flirt with
the salesperson, you could get all three? :) <--- That's a smiley, I was
jokin!

I'm in Fountain Inn, and while the GSP market is all digital, I have
found my Kyo-3035 on AMPS once in a while, especially along SC 11 in
northern Greenville and Spartanburg counties.
