I am half-heartedly contemplating
In that case, I suggest that you buy one that somebody else has completed.
Embarking on an aeroplane build is not something that should be approached half-heartedly; I suggest that with that mindset it is unlikely ever to fly.
No criticism implied - building is a huge commitment, even renovation/rebuilding is a far larger job than many folk perceive and the harsh reality of the amount of physical work can be very daunting!
