I bought the Littmann III cardiology stethoscope earlier this year for medical school because it was manadatory.  Overall I am happy with it, but the stethoscope itself is a little heavier than the Littmann Classic.  Most of my classmates bought the Littmann classic stethoscope.  Some chick in my class even bought a hot pink stethoscope.  Yes, a hot girl with a big rack carrying a hot pink stethoscope around her neck just screams “professional.”  I think if I had to buy a stethoscope again I would probably opted to buy the Littmann classic because it’s cheaper which is good because I have a tendency to ruin expensive things.
