I'm very aware of that auction. I had been planning on going to sell a Killer Instinct 2 machine of my own. Wasn't able to make it, though.
Trust me, though, I'm very aware.
However, aren't most of those complete machines? Do they even sell partials?
I don't wanna pay more than $50... finding one for free would be ideal. I can't afford anything big anyways. This is a b-day gift.
