I remember sometime back, I posted this under the "Things I
Desire But Don't Really Require" thread...
The Littmann Stethoscope Electric 4100WS Black!


This brings diagnostics to a whole new level!
And the cost for hearing heart and lung and what-not sounds in
pristine stereo, A$749.
I saw a Prof in my new workplace wearing this around his
neck!! Waaaah! Surround-sound stereo system! 
BTW, this Prof is a Singaporean, very prominent in his field,
known to be THE BEST surgeon in his area in Melbourne. Huge
brain drain for Singapore!
I speak a little bit of Hokkien and Singlish to him whenever he
comes round to see his patients.
He told me yesterday that one day, he'll bring
laksa for me!

Anyways, I digress. The reason why I'm talking about this
stethoscope is because I just told the Nurse Educator in the
cardiac ward that he should get the hospital to purchase this for
him or just for use between the Educators in the Emergency Dept,
ICU and the Cardiac Unit because it will prove invaluable in
recording abnormal heart and lung sounds, and then setting up some
sort of database where nursing and medical staff can access for
training and knowledge.
Anybody tried using it infront of a loudspeaker? 
Wonder what it sounds like.
