Another popular version and one I very much like to read is the CEV or Contemporary English Version.

Also the ESV ... English Standard Version. Although I usually read the NIV and I like the wording of the CEV for study groups the English Standard Version is a very accurate and great translation which I believe will eventually take over the NIV's place.
