Query: Nice expensie dictionary

This is a very nice paperback dictionary of Russian/English and English/Russian. The Russian entries are the Cyrillic but there are phonetic pronounciation guides that are very helpful for those who are not advanced in Russian. It seems I am constantly referring to mine during my other Russian courses. It has a nice language section in the back with all the useful phrases. I highly recommend it.
