As someone who bought this book, I'd caution against a hasty purchases of it. I found it to be excessively dry and tedious. None of the original emotional content that make the meditations so moving is present. In the meditation you can clearly see - here is a dying man asking hard questions about life. In contrast the citadel book debates the various possible translations of specific words etc. Nothing wrong with it...just tread cautiously.
I will definitely look into the other suggested translation though.
