If someone is getting you a gift, get what you like. I still have my Littman Cardio III I got as an MSI 12 years later only having replaced the diaphragms a few times. It works well for me and I use a stethoscope quite a bit in my job.
That said, if I was an MSI not knowing what I was going into I'd buy this:

Looks cool and you can get it in a multitude of colors, including the favorite all black. At 15-20 bucks you aren't going to get too bent out of shape if it sprouts legs in the hospital as many seem to do. It has good acoustics (rated just below the Cardio III in this review

When you get toward graduation and you're going into a field in which a good steth is useful, someone will probably want to buy you one for graduation. Go to town then, or just keep the S-R style. Get a few to coordinate your outfits for that matter.
