Does anyone have Devil's Backbone?

It is also known as 'Mother of millions' I think the botanical name is Kalanchoe diagremontiana?? I had a few as a young child. Unfortunately over the years I have lost the plant. I would love to replace it. I cannot seem to find it in my local area nursery's....
I would happily/love to do a swap of some kind?

happy gardening,
