Thank you for all the info. I did find out you can't really beat those Amazon prices.
After much extensive research through online shopping around, review searches on here, and even a video on the beginner & the stethoscope, I ended up going with a Prestige Medical Cardio Sprague http://www.amazon.com/Prestige-Medic...7773175&sr=8-2
And another very basic dual head, light pink back up - Just under $10, had to throw it in.
I was going to go with the Omron, but read too much of the way it hurts people's ears. I think it's cool, though, how it comes with the interchangeable bells & diaphragms.
I wanted the conveniences of a single lumen. I also read that single lumens were preferred for the beginner. Therefore, I know I'll have to own a double lumen someday as well. lol
Wanted better ear tips than I've read of on some of the other Spragues, and a dual head. The Cardio just seemed perfect, the most advanced Sprague yet.
I did read about training one's ears as well, and how the cheaper ones are most definitely preferred. That's why I threw the back up one in, just in case I hear way too much at first with the Sprague Cardio.
Was looking into the ADC's for future reference too. ADC or Littman once my ears are trained.
Sphygmomanometer shopping for a good price, next step.
