There are a couple of excellent resources on Bible translations over at the blog Slave of the Word by David Croteau. He has put together an excellent analysis comparing six Bible translations: the ESV, NIV84, NIV(2011), HCSB, NASB, and NET. David takes a look at about 50 passages and gives them each a score. The first article in the series explains his approach. And the final article in the series provides a link to a pdf of the entire series. I have found this to be a terrific series and highly recommend looking at it.
Slave of the Word also has an article providing links to a series of talks given at a symposium at Liberty University. There are talks by supporters for the NIV, ESV, and HCSB. While I have not found time yet to listen to all of these, what I have listen to so far is well worth the time.
