Online Russian dictionary

I am looking for a good English-Russian/Russian-English online dictionary. Can someone recommend me one? I prefer to get not just the translation, but also synonyms, impf.-pf., example sentences, etc.

Thanks for your help!

I have been using these dictionaries. I hope you will be able to use them for the benefit of themselves.

I usually use http://multitran.ru/
It does not have example sentences, but it does have example phrases. I am not sure that this dictionary is very useful for learners of Russian, but it is really helpful if you are looking for some specific term (i.e. related to finance, metallurgy, etc.).

http://www.wordreference.com/ has one.

Thanks a lot for all your great help :slight_smile:
