Quoted from MK6PIN:
I think any manufacturer would be susceptible to defects. It's how they handle it ( or not) determines ultimate credibility
Agreed. When I was at ReplayFX this year I noticed that the JP Premium game had the same rippling clear issue around playfield posts.-especially around the slings. While this wasn't a production game it still appears to be something that plagues all manufacturers. I do think that Stern does a fantastic job in supporting their games and covering these kinds of issues which is why I wouldn't hesitate to order from them. I haven't bought a JJP game yet so I can't comment on their level of support.
