I have so many good things about nimzovitz's my system that even though it will tough going, I am going to get it. I know there are two editions out since the old descriptive notation ones, but which to get?

One has his picture on the front. Then there is a newer one with a pawn ( I think) on the cover that is better looking inside but I hear has  lots of typos. What is your experience with these editions and with this book? Is it impossibly hard to read and is it as great as they say?
