I'm a novice myself so I don't know if it's great quality, but I bought the Oxford Pocket Kenkyusha Japanese Dictionary. It's Japanese-English and English-Japanese. I didn't feel the need to get myself one of those huge, expensive, complete language dictionary at this moment in time. It's small, light, and gets the job done. ^^

The Oxford dictionary lists things by romaji, and it supplies hiragana, katakana, and kanji when applicable. However it doesn't list by kanji, so you'll need a kanji dictionary to do that. EG) If you were looking up the word 'watashi', you would just go to the W tab, search through, and find the word. Watashi will also be written next to the romaji as わたし and 私 since it can be written as both.

I hope this helped. *^^*
