The only one you need
This is a very awesome learning dictionary - not just for looking up words but vital if you are serious about learning Japanese. Being able to save words in lists, organize lists, and then study is highly useful.
Dont be cheap. If you will just casually look up a few words then maybe a free dictionary will do the job but for anyone who really wants to learn, just spend the money and you will find that its worth it.
