For the space or for an individual?
Personally, that toolkit would be what I as an individual would be bringing with me every day to the space to do basic metalworking.
I would expect the space to be interested in purchasing more along the lines of a rolling mill, centrifugal caster, lost wax kiln, the vacuum chamber, etc.
One thing to be careful of with a vacuum chamber is that most of them cause a bloody huge mess if you accidentally manually release the vacuum incorrectly (they suck the pump oil backwards). Given that we’re a hackerspace, that failure mode will become a certainty. We should find one that doesn’t have that failure mode or has electrical rather than manual control.
However, if you really want the hackerspace ethos, watch some of the YouTube videos of various artisans of India producing jewelry. They do some amazing work with really crude tools. What is interesting to me is when they actually invest in a powered tool–that’s tells me that it’s really important.
Of course, if you really want to feel inadequate :), you have people like Clickspring who cut smaller-than-your-thumb teardrop spiral flutes freehand (CAUTION: people who have machining tendencies will get sucked into his channel and lose hours of their life):
