I generally use the NIV. Lately I’ve been using the online version at
http://www.biblegateway.com/versions/New-International-Version-NIV-Bible/
The audio version allows me to "listen" to Gods word whilst driving to and from work.
Also, I read the KJV of the bible and some times I need a modern translation, so all I do is hit the parallel option and it gives you the KJV and the NIV side by side.
I must admit, while the KJV is harder to understand, I feel as if I get more out of reading it. All other translations seem "to me" to be dull and lifeless...
