Best scope for noisy environment?

I am finally replying to my own question (there was a glitch w/ my account for a while there and I could not post any new threads or responses).

I purchased a Littmann Master Cardiology, and IMHO it's the best of both worlds: flat scope and great sound quality. I like the flat ones better.........I think I can hear heart sounds a bit better than w/ my Card III and no problems w/ BP's at all.
