If you bought the revised version, do you feel that you would recommend the upgrade? I had pre-ordered it (I have the original) but backed out at the last minute because I simply wasn't sure if it would be a wise enough investment since I already have the first version. I am now reconsidering because I enjoy and use the set often. I am thinking about calling sales and asking if they can still honor my pre-pub price (I have the email showing that I actually had called and ordered it). If they can/will, would any who upgraded recommend it or would you say let it pass and wait on something else? I have tried a Pillar volume but to be honest, my studies, so far, have not required such deep detail.
Thanks.
