I have the Welch-Allyn Harvey Deluxe, and I like it a lot. The earpiece angles are adjustable, unlike the Littmanns, and that was one of the selling points to me. It cost similar to the Littmann C III, and has a seperate diaphragm and bell and comes with a ped diaphragm and bell which you have to switch with the adult to use. Having to switch may be a draw back, but I like having a seperate bell so I don't get confused on whether I'm listening to high or low sounds. (That may sound funny, considering sounds generally sound high or low, but when I'm trying to remember all my cardio exam stuff, the simple stuff can trip me up.) But bottom line is that they are all about the same within a certain price range. I'd be cautious of buying anything I couldn't afford to replace if I lost it in a year.
