I'm well aware that Paul Sellers uses machine milled / planed / dimensioned lumber. I am quite comfortable starting with rough sawn boards straight off the mill (I'm not crazy enough to re-saw logs by hand). Yes, it requires effort and depending on the size of the project I will either use S4S wood or rip, flatten and true boards by hand.

However if I were to have machines in my shop I'd get a bandsaw first, then a jointer/planer. I'm mostly limited by physical space, not self-imposed constraints, although it is very fulfilling to build something without electricity.
