Save yourself! (mostly in jest).
Cheap materials, can be done with cheap tools, and he's pretty straight forward about what's important to worry about and what isn't.
You'll learn whether or not woodworking is for you, and you'll have a handy workbench.

Buying the sander and dust collector would probably be cheaper than all those hand planes, but there is something in that fine smoothing plane shaving that keeps you coming back.
The Sellers approach is obviously far more time-consuming than what I might call the New Yankee Workshop approach, but it has tremendous merits for new woodworkers. It's very easy to be intimidated by the huge workshops full of expensive machinery that you see on YouTube or in the magazines, but Sellers makes it absolutely clear that you can do fine woodworking with a tiny amount of space and a handful of cheap second-hand tools.
Other YouTubers promote a similar message - Rex Krueger springs to mind - but I think that Sellers offers a uniquely clear vision of how traditional skills and tools can make woodworking a more accessible and enjoyable pastime. For many amateur woodworkers, getting it done is almost besides the point - it's about the quietness and concentration of skilled manual work, the smell of the shavings, the satisfaction of a sharp tool and a neat dovetail.
