I am currently taking this course and would also endorse it as an excellent value for the money. It’s given me new things to think about, and new ways to think about things I thought I knew.What level are you and what are you looking for? Live 1:1 coaching or pre-recorded video content?
I paid for "From the Ground Up" by Pete Clarke on Run It Once. It was a set of videos and it was good value for money.
You can watch the first two video for free at that link.
