Picking out a new stethoscope

I am in the process of selecting a new stethoscope after using a no name brand for a few years. I have pretty much settled on a littmann single sided design. I am aware that they are a little harder to use but I have experience with them from EMS. I was seriously looking at getting the littmann cardiology STC from medisave.net (free engraving) due to it's nice grips and long warranty of 6 years. Is there a drawback to having a stethoscope that is "too good". Can it pick up too much detail. Not that I would know what to listen for anyways (one day I might) but would I be doing myself a disservice by getting such a good stethoscope?

Thanks,

Joe

Also, Can't take credit fo finding it but ran across it in another thread so I'll post it agian to spread the word. If you buy from medisave.net make sure you click the checkbox that you are a student (if you are) and you will get a voucher for a free accessory kit (only if you buy higher end models) and use the coupon code "backtoschool" for what I believe to be 5% off.
