Looking for digital recording equipment ideas?

My daughter is 17 and is very interested in possibly going to school for music producing. She and her friends have their own band and want to record and mix their own music. I thought this would be a good chance for her to try some of her own mixing and producing but I don’t really know much about it. I was hoping someone can give me some ideas of some inexpensive equipment I can buy her for Christmas to get her started?

Any Ideas??
