On the blog, What I learned from Aristotle, Philip Comfort's book, the New Testament Text and Translation Commentary is positively reviewed.
I picked up a copy of Comfort's book at the SBL in Boston, but I have just had the chance to use it a couple of times, so I cannot really access it yet, but it does look user-friendly.
See also Bill Warren's note about the book here. In the comments Peter Head said he would put it on his shopping list for the SBL, but I know he got his copy for free there because the generous author was in the booth (not when I arrived though...).
Kevin Edgecomb and Nick Norelli also have comments on the book, here, here and here.
