As I said in my review of the Stambaugh/Schmidt translation I really like the Macquarrie/Robinson translation partly because it is the first translation I read so I got used to the terminology and partly because Macquarrie and Robinson give, I think, a better sense of the German by choosing slightly awkward translations (like ready-to-hand and present-at-hand, etc.). I do not read German but I have read both this translation and the new Stambaugh/Schmidt translation so I have a few comments about their relative virtues. I should say a word about this particular translation. It also focuses more on the second division which is really the more important division though it is also the more difficult division and for precisely that reason it often gets less attention in the secondary literature. It is not the easiest or most accessible of the commentaries on Being and Time but it is one of the more accurate in my opinion. Personally I would recommend A Guide to Heidegger's Being and Time (Suny Series in Contemporary Continental Philosophy) by Magda King.

Unfortunately a number of them are very problematic. There are a number of books that attempt to make Being and Time more accessible. It is not a book that one should try to read without the necessary background (some knowledge of phenomenology) and, ideally, without some guidance (i.e. Being and Time is, obviously a ground-breaking work but it is also a work that frustrates many readers.
