I know a bit about both schools, however I do not know about their pricing system. I still think your idea of checking out both schools is a good idea. I would also participate in a free class if the offer one. I can tell you that you are going to get a heck of a workout at either school..plan on coming home exhausted. They are both licenced by the same Krav organization, so the Krav training should be near identical. Only you can make the final decision based on your perceptions when you look each school over. Also keep in mind that Krav is a departure from your past MA training. Make sure it is what you are looking for.
All the best!
