What stethescope should I choose?

Hello everyone!
I am going to try and buy all of the things that I will need for school over the Summer to avoid having to purchase them all at once. Our school bookstore sells stethescopes, but a friend that is in the program now said that hers was not worth the money and she would advise me to buy one somewhere else.
The problem is, which one do I choose? I worked in an ER about 6 years ago and I remember that Littman was a popular choice among the nurses. There are several new Littman Master Classic 2's on Ebay right now at very reasonable prices. Will it be worth my money though? I'd appreciate any and all advice. Thanks!

if you can get a good one at a resonable price on e-bay go for it. Everyone needs to listen to lungs and bellys but some need to do more then others. In Labor they get a quick one over but not like they would were they in ICU.

Thanks Cassioo...Is the Littman Master Classic 2 a good one? I'd rather go ahead and spend a little more money (but still get a deal on Ebay!) and have one that will last for a while than spend my money on one at school only to have to replace it!
