I believe in investing some money in a good stethescope which is what I did. I have had mine for 7 years and it was worth every single penny. I cannot hear with cheap ones. Be sure to mark yours very well and if a MD decides to "borrow" it, you should keep a close eye on them. Honestly, I have had several docs hand it back to me and say "wow.. that is a nice one..where did you buy it". I think that when they know you have invested the money ($300), they are more apt to give it back- at least that has been my experience.
good luck
