Hey everyone! I'm in the process of ordering a Littmann Cardiology IV™ Stethoscope for medical school and I'm wondering whether or not to get the standard finish for the chest piece or the black finish. I've attached the images below. The black finish is $25 while the standard is $0. If it's more expensive, what benefit if there to the black finish? I'd greatly appreciate any thoughts or suggestions. Thank you!
