This headline is from the bottom of my heart. I have seen crappy translators before. As my line of work requires me to translate sentences from Japanese to English, I found that most of the so-call translator just cannot do the job properly, except for Excite.co.jp translator.
At last, found one that fits the bill of easy to use, in English Language and able to translate at the same time to many different languages.
The name itself is also nice. It is called NiceTranslator.
Here are some example from nicetranslator
It also have many other languages that you can translate.
However, please do not feed it with paragraphs as it may not work. I think the reason for it to be so good is because it gathers the public feedback to get the correct words translated.
