Tournament Insurance

My high school's martial arts club is planning on hosting a tournament for high school martial artists in the greater Sacramento area.
Insurance is a problem, so we were thinking about going through karateinsurance.com because they can insure the whole event for under %500.
Does anyone on this site have any experience with karateinsurance.com? if so, would you recommend them?

i dont know but you can probably call this place, martial arts group, 1800 207 6603. they are the cheapest insurance. insurance for schools is cheap here, and its just a little bit when you throw a tournament. try them
