:) To answer your question i was thinking more along the line of any drugs because i am going to be working in a hospital and it would be nice to know. I want to not have to change the memory on it and also i want one that is colored and i was looking it up on the internet and the one they said that was the best one for nurses is the Zine 74 it has great memory and it is colored and has a camera hooked up to it. So if you have any suggestions i would love to hear them . Thanks again in advance. ps. I live In Howell Michigan.:)
