Quoted from Caviel:
It was me that brought up the question initially. It is crazing, and some of my inserts look just like what you
posted. I'm still learning these sorts of details as I'm getting deeper into the hobby and didn't know crazing is somewhat normal.
JP is my first NIB table, and with the other reported JP playfield issues combined with not seeing this on my other two tables, I was concerned this was a bigger issue than it really is. I'm a player, not a collector, I'm just doing my best to take care of my pins and learning as I go...
I wouldn't call it "normal" but it does happen. Although I've owned many pins in my previous go at his hobby, JP was my first NIB also so I was a bit surprised about the tweaks/"repairs" to do right out of the box but I'm comfortable working on pins so not a big deal for me.
I find too many people make a parallel with buying a car and wanting it to be perfect (mostly because of the high cost involved). I have moved on from that state of mind and accepted that this isn't a collector's item, but a commercial money making device. A better parallel would be if you went out and bought a forklift, or a dump truck. Would you expect it to be perfect? would you go over it with a magnifying glass?
Now I realize some people had major issues with the T-REX (beyond just making adjustments) and that's a different thing. Those are warranty issues and I think in most cases have been dealt with appropriately (unless you expect them to come install the parts in your home)...
As long as there are no major defects that prevents the machine from working or clearly broken items then I don't sweat it. Remember that despite the high cost, it's a choice to buy one of these things. Nobody is being coerced and it certainly isn't a necessity!
