Great video, and it gives a good bit of behind the curtain information as well as helpful insight in choosing products. Badger has long been one of my favorite companies for airbrushes, though whoever that illustrator was who helped them develop the Sotar ought to be punched in the face. I bought mine 12 years ago or so...and paid that retail price point for it...
I would just point out regarding one issue in the video regarding thinning. Specifically, they are talking about Minitaire paints...but some people might get the segment out of context. Several hobby paints are actually alcohol based. Tamiya, a good portion of the Mr Color line, some Valejo, a lot of inks... Allof those should only be thinned with alcohol or purpose made thinners. If you attempt to thin with water...you will have the same problems that you have with thinning water based paint with alcohol...the potential for gumming up the internals of the brush.
