For a 'beginner' film I strongly recommend Ilford Pan 100 or Pan 400 - not to be confused with Pan F. It's not particularly easy to find since it's only really sold here as a student film but if you can get some it should be cheap and good value for the money. Apparently it's not the best for 'critical applications' but then are you really going to be printing huge enlargements for professional purposes? It's easy to develop yourself and produces high-contrast negatives (in my experience; it was the first film I used when I started developing my own film).
