They're both good choices, but if it's one or the other, then personally I'd get the DNA200, it'll have alot more customizability using Escribe.
The questions I have for you are:
- Do you understand LiPo batteries and their charging characteristics? (Are built in batteries an issue for you? like having nowhere to charge it throughout the day, should the battery die).
- Is he offering them to you at the same price, or is he charging you more for the DNA?
- If he's charging you more for the DNA, then do you actually have a use for it? (Will you actually use Escribe to customize it's functionality, or are you a plug-n-play type person?).
The answers to these questions should be the key to deciding which route is good for you.
