If I remember correctly the vibe machine is priced at $18,000 which is an absolute rip-off. Plus I think that it uses older tesla technology but don't quote me on that. The VE-1 and VE-Pro use better and newer technology and are priced cheaper...in the case of the VE-Pro it is priced a lot cheaper. Next best alternative would be an MWO from Dan Dial which is around $1,000. These machines are amazing for cancer patients but other things like huge doses of pancreatic enzymes, and ozone/oxygen therapies should also be used.
