I'm officially on a Internet hiatus because I'm unwinding in the frozen flatlands of Michigan but i resurfaced for a short while to buy nursing supplies online and I'm popping my head in to voice my frustration. I'm buying a stethoscope and I'm down to deciding between a Littman Classic II SE or a Littman Lightweight II SE. so far I've got equal votes for Classic and Lightweight. spend an extra 30 dollars on a better 'scope, which will pay out in the long run? or is it not worth it if I'm only doing blood pressure and the like? or should i not compromise on sound quality just to have a more comfortable, lighter stethoscope????
