Off the top of my head, I would say that I would choose a Vitalizer Plus, and use it with the distiller I already have. However, that doesn't mean much, because I am not too familiar with the benefits of ozonated water, which really might be more beneficial than the vitalizer water. I suppose there are cheaper ways to "vitalize" water (like putting it in the sunlight). So if I did some research, my answer might become the ozone machine. Maybe. But I definitely think the vitalizer would be good to have (although I would use it without the mineral block thingie).
