Beautiful eBook formatting is not expensive; in fact, it's more reasonable than you think. For years, I paid handsomely for someone to format my eBooks, not to mention I had to wait a week or two to get it done; now, I do it myself. I save money and I get it done in one night.
Aren't your readers worth more than a plain-vanilla eBook thrown together by an automated conversion system?
Don't they deserve the best?
