If you know kana, there's no need for a dictionary with romaji (which both of these seem to be?). Kodansha also do a furigana dictionary, Oxford have a few options including a beginners and a mini dictionary.
What do you want the dictionary for?
e.g. is this something to have at home, on your bookshelf as a reference item.
or is it to take with you when you travel - e.g. something more portable.
