Looking to order persimmon rootstocks, big? Cheap?

I paid $10 plus shipping for my American persimmon seedling from Schlabachs last year. It had nice roots. Small trunk size though. Look up the thread below and you’ll see a picture.

By the way it was my best performer last year. Probably grew about 4-5 ft ( I gave it urea).
I grafted to it this year.
