Littmann Cardiology STC?

[atn18]

Hey there! I was debating between getting a litmann Master Classic because I hear SUPER well with that stethoscope after trying a few. I was trying to save some money and get a used one but someone offered their barely used Litmann Cardiology STC for a decent price.

I never heard of it so I googled it and saw it was discontinued. It has AMAZING reviews and was ranked highly on the Littmann comparison chart. However, does anyone know why/when it was discontinued in the first place?

I'm just curious to why was it discontinued and whether I should just buy my own new master classic or try the older, cheaper, discontinued STC? Lol! The STC seems awesome and I'd love to save money but not if there's an issue with it.
