This came through this morning and may be of interest to some. I've never heard of it in a veg context before. They do seem to be rather expensive but I'm wondering whether the alleged benefits might continue if one saved seeds, thus making them a better investment over time.

I think if you save the seeds from grafted plants you it will be the same as the top part of the grafted plant. You wont get nay benefit from the rootstock in the seeds.

You would need to keep buying the grafted plants each year or create your own grafts.
