I'm wondering if anyone out there has heard of or devised a listing of kit and equipment and its cost, weight, volume, and performance at different TL's? If not that, then has anyone come up with a methodology to calculate these values? For example, PRIS binoculars become available at TL 12, but let's say you want to buy a set manufactured on a TL 14 world. There are bound to be differences in cost, weight, vol, performance, etc. Same goes for almost any conceivable type of item. Can anybody help?
