nutnfancy (he's actually decently knowledgeable, he just annoys me to death and comes across a little conspiracy-ish)
When I first came across NutnFancy's videos I didn't care for them. He seemed kind of arrogant and he is prone to rambling which I think sometiimes makes his videos a bit longer than they need to be. However, I stuck with it and watched quite a few of his videos and they grew on me. I still think some of his vids are overly long, but they are packed with some decent information.
Hickock 45 and Military Arms Channel are also great!
