Electronic dictionary

A must for Japanese learners is a electronics dictionary. I suggest buying a dictionary which does not have too many features as some may confuse you.
The following I recommend
English - Japanese - Japanese & English Talking Electronic Dictionary EJ400T
Sharp Electronics PW-E550 Electronic Dictionary
Ectaco Partner EJ400T Talking Electronic Dictionary English-Japanese

But if top range is your thing then ECTACO Partner EJ900 English-Japanese Talking Electronic Dictionary and Audio PhraseBook is a must
