You can watch the first lesson on his YouTube channel to evaluate his delivery and teaching style. I happen to believe that Nick is a talented photographer and he pays a lot of attention to light and generally is meticulous about all things, something I value. His teaching style is superb IMO: informative and entertaining. $200 is just two dinners, totally worth it.
Teaching is a skill. Simply knowing is not enough. I wouldn't take anyone's lesson unless I value their work and saw them teach. Carver is an excellent photographer and a great explainer. 99% of people here do not share their work so I wouldn't know if they're worthy to be learning from.
Otherwise there's risk of "learning" from someone's parroting things they read somewhere else on the Internet, which can easily be utter nonsense like your post above. How can you say that the class is overpriced and a better version is available elsewhere, if
you have not taken the class? You don't know what's covered. Why are you even replying? You literally have nothing to say on the subject, except to demonstrate the level of "teaching" that's available for free.
