Our school recommended the Littman Classic II SE, which is around $80-90 and what I got. I am just getting ready to start Med/Surg, so I have used it for a little bit and it seems to be working just fine for what we need. I would recommend it.
We weren't required to purchase any BP material as the hospitals/nursing homes all have those, so I don't have any myself.
Best of luck!
Edited to add: Clinicals are absolutely wonderful, you will love them! Don't let people scare you about horrible clinical experiences, wait until you're there to make your own judgements. Enjoy it, so far every step of the way has been wonderful for me!!! Oh, and even if you're scared, volunteer to do skills if you get the opportunity, there is nothing like hands-on experience and the teachers do notice.
