If you are looking at the value of time, you are missing the point of building. For that matter, if you are looking at the cost of a kit or ARF or scratchbuilt, you and missing the point. Most of us that build kits or scratch build do it for the pure fun and satisfaction of the build. It is a hobby unto itself. If you choose not to participate in this hobby, it does not make you any less a flyer. You can make the same study of kit building a full scale plane vs. buying a certified aircraft. From a cost prospective it does not wash. The only justification for building is for enjoyment of the process.

... but, that's just me.
