I know this is completely irrelevant, but the end of MS2 is coming up soon, and I need a steth by march for internal med. I've been eyeing a red littman cardio III. Will this be construed as unprofessional, or will I be confused as a nurse? I The choice is between either red, grey, or black in order of preference. What color/brand of steth did you get for med school? p.s can someone reccomend a good website to order cheap steths? I'm looking at www.medisave.net for the good prices and free engraving. Thinking of buying my penlight there too. Thanks!
