The VGS-1 is an optional board that has to be installed into the receiver itself.
I have a TK-2180 and my whole department uses nothing but Motorola's (HT750, HT1250, CDM1550s, Etc) and they all think (and know) my KW outperforms them. For some reason, I have a much easier time hitting repeaters than they do (both are 5W). It also has a clock built in, which is very nice so I can record the dispatch time on my runs.
The Li-Ion battery is only 1700MAh, but does not have the memory charge effect of the Ni-CD or Ni-Mh batteries. The other two optional batteries Ni-Cd has 1400MAh I believe and the Ni-MH has 1900MAh. The Li-Ion has a decent battery life (never left me stranded, I've gone ~24 hrs with an open scan) but the 1900 is what you want for extended life, but will also have the memory charging effect.
It also does Amateur quite well! Programming is easy (if you have the software/hardware). Its all MIL-spec. I've had it in pouring rain on accident, dropped it more than 10 times since I've had it. Nothing will hurt it. Has paging option. Easy to select channels (versus HT750), and lots more channels! 128 talk groups with 128 channels each! Definitely my favorite handheld ever.
Will, check your PMs.
