Which stethoscope? ?

Hi everyone! I am new to the boards, and I have some questions. I just enrolled in my CNA course that I have to take before I can start in on the nursing coursework. We are required to purchase a gait belt, stethoscope, and watch with a second hand. Please give me recommendations on these as far as quality, affordability, and ease of use. Also, please let me know if there are ones I should avoid. I definately want to do a little research before I go throw a bunch of money at this stuff. If possible, I would love to buy items that I can also use when I am in nursing school! Thanks
