There's no predators to end up with. There's just black #1 which Kevin doesn't even have possession of anymore (it's on loan to a guy in Chicago, so says rumors), and the sole production predator #2 which Tim has. and I can't see tim ever selling it.
That said there are parts to make a predator, but not enough parts (as discussed earlier, ramps are the major stumbling block.) as for the parts, many were given to people that worked with Kevin. A lot of these guys took parts with them when they left the project because Kevin didn't have any money to pay them. So they ended up with miscellaneous oddities. Kevin probably still has some things like all the back alley creation parts (since it appears they delivered all those parts in full for the entire project.) but a lot of parts are in very short supply, like say playfields and plastics, as only a test run of those was produced.
Making a predator is no easy task either. It is extremely complex and would take a lot of time and knowledge. What I heard it took Kevin three weeks full time to make predator #2. I'm not quite sure how he would've kicked out 200+ games, as it could've taken close to forever to get it all done, unless he really streamlined things. like what spooky pinball does. Of course Kevin was hand making the complete wiring harness, which is probably the biggest time suck in the whole project.
To the people that have playfields and plastics, I'm not quite sure why they have them. I know they all have dreams of making their own predator. But to be honest, I don't really see this is a feasible option unless you really know a lot about pinball in general. And have lots of tools and patience. The bill of material costs, minus the playfield and plastics, is about $2500 (proc boards and computer and dmd and power supplies (four or five of them) compromise a good chunk of that number). That just get you started and you haven't even gotten the playfield, plastics or ramps yet. It's doable but not for the faint of heart.
