Here is a legal way around this particular issue. Though there is a lot of trust and good will required, a person could buy this

and then sell it, when done, to the next member, lets say for $100 or $50 off. Eventually it will have been paid for to a more reasonable cost for most. Lets say $300, which it would easily resell for. Then it is just a matter of buying it for a short time with an understanding to pass it on to the next for the same price. This goes along with a military practice of selling a used car to the guy rotating in to a duty station from the guys rotating out. It becomes a 'base car' that everyone enjoys. The only issue comes with maintenance and/or a 'dickhead' getting in the loop and ruining it all. Not a perfect answer....... But an answer.
Though pushing this, probably a bit too far (I don't know for sure), you 'should' be able to have a party were everybody buys and sells the CNC machine in one night so a build party is possible. Technically nobody can stop any of us from buying and selling a thing. There is no limit or requirement for how long. I have every right to buy something for a short period and to expect to then resell it. One day we could see the "Forum CNC" up on the Trading section????
