Quoted from Asael:

The lightning looks good and will be better with the premiums and the LEs, but I like to mod my games and I don't think that a stock ST can top the modded lightning on my AC/DC or Met.
The sound is great from what I heard in the videos.

Quoted from markmon:

I am questioning woz build quality. After maybe 600 plays, my shooter lane clear coat is starting to flake off already. The center post came missing a nut to tighten it. The right flipper switch wasn't adjusted correctly and wouldn't trigger the castle upper playfield flipper at all. The light boards are dying once a week. I have two rma boxes from JJP and another will die before these are back in their hands. Of the 30 games in my house, the woz has broken 8 times so far. The game computer bios has also gotten itself into a state where it wouldn't boot anymore and I had to download the motherboard manual from msi website and figure out where the PC case header was at. Then I had to jumper the power button wires to get the game to turn on.
They've redesigned power boards but seem reluctant to send us guys stuck with boards dying weekly new upgrades proactively. They saved 50c by not installing a PC switch button like pinball 2000 even had. Yea. The build quality isn't amazing. I'm tired of hearing how it is. Adding a few pounds to the cabinet doesn't make for a more reliable machine.
If your complaints with stern are build quality, QC, and unfinished code, then why are you considering JJP a solution? My woz had worse QC than my last few sterns. None of them came missing bolts and flippers dead. My woz is down broken more than all my sterns combined. The code on my woz is more unfinished than sterns latest, Star Trek.
Btw, its not just me. Two local ops are having massive problems trying to keep their games running. One tech is green and he calls me every week for help on the woz repairs.
Don't misunderstand my post here. I'm not saying woz sucks. The rules are getting better. With the recent code update, for the first time the game is actually fun now. My game is working as of today. Although it did break down Friday. Anyways, pinball comes with a cost of ownership. If you think JJP is solving all the recent stern complaints, sorry but you're wrong. Its far from the truth.
I'm keeping my woz, I'm full paid on hobbit. I own several sterns including Star Trek, Metallica, and xmen. This is my unbiased opinion and experience.
