I think getting the schematics for certain things is way too hard / luck reliant, thats where research table would come in handy. As an example finding a shotgun but it's level is too low instead of scrapping / selling it you could research it then recraft it afterwards. To balance it out it there should be a **FEE** which scales with quality level, lower level higher FEE, if its made out of steel u need to pay some steel, if its wooden pay some wood, etc... Research table should be a high end item level 4 / 5 advanced engineering. It would be nice if you could research item parts as well ( shotgun parts, steel tool parts, etc...)
