20K is rediculous. I offered 2k and got mocked. Seeing as no one has offered anything different, why not ask this guy what he wants? If it's 20k were all wasting our time.
I'd also split revenue with him for three months on these, I pay power costs.
I just told everyone what he wants, 23K for everything.
These non traditional split revenue, let me host it for you in my leaky shed type of arrangements are difficult as it's difficult to find someone you fully trust. If you have some brilliant plan you can always PM me your contact info and I can pass it on to the seller, but mocking offers will get you ignored.
Let's put it this way guys, if 2K was an acceptable offer I would've bought this gear myself as it's already running in our shop.
