I use NIV, NKJV, NASB, and KJV if I'm posting for KJV Only people or speaking to them (in order to not get them mad at me)
However, I have read from many translations, and there are only a few that are *all bad* (the New World Translation of the Jehovah's Witnesses, Joseph Smith Translation of the Mormons, and the Buddhist Bible are basically the only ones I loathe for being biased, wrongly translated, and worthless in a study of the Word of God)
One more thing: I know how debates like this can go, so I am begging the mods to stop this if it becomes a KJVO debate. We have 2 of those over in Bibliology and both have reached the stage where a screaming match with a telephone post would be MUCH more profitable to all involved.
