What do you think of your electronic stethoscope?

i'm graduating in may and one of the things i have on my wishlist is an electronic stethoscope. i talked with one nurse this weekend who had one and she said that she didn't get what she was hoping for.

so, here's what i would like to know:

• if you have an electronic stethscope, what kind to you have?
• what do you think of it?
• if you had the choice to make again, would you still buy it?

thanks!
