Sure, its been a while, but I'll jump in here.
Yes, I get supplied by my company (I'm a basic for an IFT company) with the el-cheapo double lumen stethoscope that creates all sorts of noise when the tubes rub against each other and hard black ear pieces that rub your ears raw if you tilt your head while wearing it and the seperated gage and bulb B/P cuff, but I still bring my own (actually, I got the BP cuff for Christmas).
I got the steth early on. DRG Symphony (~$40, decent steth, but still cheap enough that it won't hurt too bad when it grows legs and walks). I love having this stethoscope. The gel sealed ear tips makes it easier on me, I can actually hear something with it, and I don't have to worry about who used it last shift.
I've only had a few days so far to use my new cuff, but I won't be going back anytime soon. Trigger grip with integrated gage makes it so much easier and faster to take a BP now that I don't have to worry about balancing the gage someplace and it is easier to control the speed that the cuff deflates at.
Is it needed or expected to bring your own? Nope. Do I feel that my job is easier by supplying my own gear? yes.
