I heard recently that there is a new translation which is rather good for the modern reader. (http://www.amazon.com/The-Emperors-Handbook-Translation-Medi...) I think I heard about it on the excellent "History of Philosophy: Without Any Gaps" podcast, but I'm not certain of that. It can seem silly to spend money when you can get the ideas for free, on the other hand, the style of translation can easily get in the way with ancient writers and old translations. I've quit reading a couple of dry translations of the Meditations when they would put me to sleep rather too fast during bed-time reading. I've got the new one on my Xmas wishlist and plan to buy it in the new year if someone doesn't get it for me.
So maybe check it out if you find the old versions slow going.
