Mine is #69 and built 2/11. I have one problem that is nagging and consistent but 100% fixable I just need time to deal with it.
They have bound the wiring so tight that any movement of my PF (in or out) knocks off the 3 connections on the far right hand board in the head. Its freaking maddening! I have clipped wire ties, loosened up the bundle in multiple spots and still have the issue. I am going to have to "mount" the wire loom up inside the base cabinet enough to leave slack up to the head so that when the weight of the bundle hits those connectors they don't come off.
I just got my game last night and pretty much didn't get to play due to this issue.
Basically I scrapped playing last night and just put my mods in place instead. Again this issue is 100% fixable I just need the time to get it done.
I can also say that Yelobird is 100% right this game has to be level and pitched right. Until I did this last night the ball would get stuck in multiple places. Afterwards rolling the ball over the PF through loops etc no problem.
