I agree with the comments about eDict - I personally use it as a last resort, when I can't find a word in my main dictionary. My favorite: ウィズダム英和・和英辞典, just had an upgrade to 2.0 - overall, the old GUI was prettier/slicker, but the new one is actually more functional.
They >finally< added a jump feature so the sample sentences are now extremely useful - if you can't read a certain 熟語, you can just select it, and it will automagically jump to that entry. It also looks like they implemented copy-paste, bookmarks, and history.
They also added several new features that are very useful - the top left button now cycles through 用例 (sample sentences)、見出 (discover) 、and 成句 (set phrase)。All are quite useful. Most of the time, I just want to see a bunch of sample sentences, but discover will show entries that combines your search with other words. Set phrase is useful for finding expressions with special meaning.
A bit of a warning, though - this is not a beginner's dictionary - it is best for intermediate learners (about JLPT 2) - actually, this is not as true any more - with the jump feature, even JLPT 3 level learners should also benefit... ...but beware - there is no furigana (IMHO, that is a good thing), so you should be comfortable with some Kanji.
