Quoted from mechslave:
The build of WOZ is all I have to go by, but it's a rock solid aircraft-quality build compared to some Stern stuff I've received.
WOZ has just as many issues, you just don't hear about it because the owners hide them all in the JJP forums which are private, because they're afraid of getting mocked and abused here. Which is lame on both sides frankly.
Repeated LED board breakings, power supply issues, clear coat chipping, pop bumpers creating metal shards that wear the playfield to the bare wood if you don't deal with it, monkey magnets, castle ball guides, slippers falling off, blah blah.
It's pinball, shit happens. I'm not dumping on WOZ, I'm simply saying that things aren't perfect. There's no magic in the JJP factory. Just like they weren't perfect on the original WMS built MM. If you're not willing to fix and adjust some things out of the box then don't buy NIB, get a dialed in HUO machine where someone else did it for you.
You know what WOZ has over most Sterns? Higher BOM. It's the parts that determine a good portion of the quality, not who put them together. Rick is still in charge of that part.
