I like it a lot.Since I'm anal about mpg,during projects,I'm apt to let record-keeping fall by the wayside,and its very difficult to tell what I've actually invested in any particular project. And this is exactly what matters most to some people,when they ask me about my contraptions.Some kind of life-cycle-cost-analysis. If we can record and compile this kind of quanta,some potential modders should be able to build their projects completely on paper first,and know if the whole ordeal is going to be worth the expense in material and manpower before they ever leave for the store.Good one!
