Software to assist qualitative analysis


I am about to embark on gathering 20 interviews (at about an hour each) and plan to explore this using template analysis.

From what I have found I would rather use a computer aided approach than do it by hand. My university does not provide or train in any package. Can I ask for recommendations of software that does not have too steep a learning curve and which is reasonably priced as I will be paying from my own pocket.
