Up to you, but as an amateur I'm sure you could appreciate being able to program on the fly. On the other hand, these have enough memories (1024 channels) to make it easy to program in all the simplex frequencies in the 2 meter band, add a manual PL selection button to change CTCSS/DCS tones on the fly. Still lots of space left over for repeaters and public safety monitoring. If you really are hard up for space, you can add a 4000 channel option with KWD-5000CH $420.00 (hey, it's just money....)
Remember, these are LIST prices. Under state contracts I get 30% off. Buying as an individual, I'd look for 15-20% off.
As for these over Motorola,
I spec'd one of these out for our PD to install in one of their vans. They're running TK-5710's everywhere else. A few years ago we switched them from MCS-2000's and XTL-2500's. The officers were very happy with the new radios due to much better audio. They really like the NX-5700 with the color display and great audio.
I like them because Kenwood has been orders of magnitude better to deal with than Motorola and their shops. The officers like the radios, and that makes my job easier. Chief likes them because they are cheaper to purchase.
