I like Miles Beckler. His videos are single take efforts (even the hour+ videos) and his passion screams through them. He doesn't monetize his videos, instead choosing to rely on affiliate income because that's what he's teaching you.
But recently I came across WPEagle, a channel by a pretty down to earth guy that just teaches you how to actually implement affiliate marketing sites with wordpress. I like him because he's very transparent and matter-of-fact with his delivery. His videos are like "I did this, it took this many hours, it cost this much money, and here's my net profit" and he actually shows you his amazon and adsense dashboards.
