Same price at the conference....I sorta put them in order of ones I like best. Some of the other talk titles sound fabulous but they weren't very good. For now just get Jerry Brunetti's talk from weston price on iodine. It's great and is $15. Then go over to Acreusa and get Dan Skow's talk on brixing from the 2004 conference called rediscovering the refractometer. That's $8 and those two should give you a good overview of minerals for health from a wide perspective.
All of orlee's talks at acres are downloadable for free on his site so no need to buy them.
But if you want one more I'd buy....John Dommissee on B12 from the 2005 WP conference. Made me truly reconsider never ever letting my B-12 levels drop low...and low for him is the Japanese standard not ours.
