Nobody's mentioning what I think should be obvious - a table saw, an impact drill with kilograms of sorted bits, whatever stuff you need for welding. Soldering equipment + as many schematics of the PCB based stuff I own with enough spare parts to drown in. Kilograms of copper wire. If there's no weight and space limit on this question, I'd get a car lift too. I really doubt that anyone would be in dire need of my sick ability to manually inject a DLL into the memory of a process if they were eating each other.
