From the looks of the machine I say it looks great and the only complaint I have about it from the videos is the ball locks/upkick that are shaped like metal cylinders, these look built well but they are just barely bigger than the ball and when the ball locks in one it seems like it takes a while to settle like a penny spinning on a table as its dropping if that makes sense. From the video that seems to slow the game down, I think they need to widen that cylinder just a bit.
Now I'm not buying a WOZ because I wasn't fortunate enough to get on the presale list so I bought an ACDC instead and can't afford another 7k pin at this time. I will be buying predator and actually love that they are selling it at an affordable price #45 here.
I'll probably be on the list to buy JJP's second or third pin but we'll see. Looks like woz will be a good one though.
