The biggest thing you have to look at is the type of films you will be working on and how often you will be doing it. Basic software will do only basic functions, such as simple cutting, compiling, transitions, effects, and titles. Along with this is usually a very basic amount of export options. This is often good for home videos, such as sports games and family trips. If you do not intend on doing much more then it seems as though you are not going to need to spend the hundreds, if not thousands, of dollars on professional suites.
