I am shopping for a new stethoscope, and I am thinking about getting either a Littman Cardiology III or an Ultrascope. What I am seeing by browsing threads on this board and elsewhere is that once users have tried an Ultrascope, they never go back to using a Littman, no matter how pleased they originally were with the performance of their Littman, even if they had been using a higher quality one like the Cardiology III. My question is this: Is there anybody out there who continues to favor the performance provided by a Cardiology III after they have tried an Ultrascope? Or is satisfaction with a high quality Littman largely dependent on the user never having used an Ultrascope? Please tell. mykal
