ASA is a lot cheaper but their speakers make some factual mistakes you should watch out for. The production quality is a bit on the sloppy side but the price is very good (something like $75). King videos are better made but require installation on your computer to defeat copying which negates using them for reference purposes after finishing the course and they cost a lot. I would not get them unless you are loaded and your school requires them.
