If you are an author considering what route to take when your next work is ready for publication, you should certainly consider the more independent route over traditional publishing. As with any business decision, you must weigh your own personal situation and decide what is the most appropriate approach to take.
In addition to the financial costs and implications, you also have to look at your own capabilities, resources and interests in deciding how to best publish, market and distribute your book(s). Before taking the plunge always do your research and make sure you consider everything from a balanced perspective.
