I shot with the RED the other week and didn't pull the meters out all day. Just looked at the histograms and scopes.
Kind of scary for an "old school" guy like me. I didn't really realize until after the shoot that I hadn't traditionally metered all day. Of course I've been lighting things for 25 years.
I believe that Sekonic makes a meter that does, spot (reflective) ambient and flash. I don't have one of those as I have half a dozen meters that are all single purpose but I my gaffer loves his.
Don't get one used unless you are prepared to have it calibrated, and I don't know where you can even get that done anymore. If you don't have someone else's meter or a group of other meters to compare it to you could be starting off with a bad base line. That being said there is very little that can go wrong on a digital meter that won't be obvious.
Best advise I can give you is don't work for the meter. That means as she is learning make sure she is using the meter to confirm/enforce what she wants to be doing with her lighting. Keep track of her ratio's (key/fill/rim/BG) until she knows what works for her and see trains her eye.
