My wife will be starting her accelerated second degree option BSN in 1 year and I am getting her at steth. for xmas. By simply reading many reviews on the Littmann Clasic II S.E and the Littmann Lightweight 11 S.E., I can not make a decision. It seems only someone who has gone through, where she is headed, would only know. So, can someone give me some "hands-down" advice? Thank you. (the difference of $30 is not an issue)
