Well I think that's bit of a red herring; how do KJVers feel about the KJV being commissioned by a bisexual? Does that invalidate the translation? I'm only really concerned with the text.
I read the NIV as a non-Christian; I understood the Gospel from it and got saved in my roon late one night. I do think it presents the Gospel clearly. There may indeed be more accurate translations and no doubt I'll come across them in my studying, but for now the NIV is sufficient as a devotional Bible for me.
You might want to consider the CEV for your daughters; I don't read it much but my non-Christian husband bought himself a copy and finds it easy to understand.
