Quoted from Gatecrasher:Total BS.
The IPB version was superb unless you got a second. One of the best reproduction backglasses ever made. Just like the IBP Kiss playfields were.
I still have one as well as an NOS and you cannot tell them apart unless you really know what to look for.
I'm not saying that the new PPS ones are bad either (because I don't purely rely on what I've "heard" and prefer to judge for myself). All I know is the IPB Kiss backglasses were awesome as long as you didn't buy a second or a reject off some crook on eBay.
I bought one of the IPB glasses off of Ebay many years ago. Would you care to detail what to look for to determine if it's a reject? I recall mine looking fine.
Wish I'd bought one of the IPB pfs when they were $400 on Ebay! I kept putting it off..
