FWIW I don't have any cash in pre-paids or purchased items from John. I've come close a few times, but never pulled the trigger.
Near the beginning of this thread 6 years ago John said he was only going to be making 40 Stargazer pfs. 3 years ago he posted he had made 74 Stargazers at that time. New people are seeing this thread years after it started and getting put on a SG and SW 'waiting list', and people are still getting SG playfields today. It has been said he works on SGs while waiting on Seawitch pf parts, but he's still causing/creating time to be spent working on new SGs that could be spent on Seawitch (or finding and going through boxes looking for pre-order paperwork). The problem with some of these new Seawitch pfs not being 100% and selling them as 'seconds' is that it makes new buyers happy, but still leaves those 5+ year people waiting. 'Seconds' by definition are usually several defective items from a massive run of product, not four items out of a run of five. The backglass reproduction, though apparently perfected, also eats into John's available time where obviously every minute counts.
John is a good person at heart. In the early days (12 years ago?) of his Space Shuttle pf re-inking efforts I was a very harsh critic of him taking pre-paid orders without having a perfected process or finished product. I regret a lot of that and apologized to John in person when he came to the Florida A.P.E. arcade show years later. I think he gets in over his head on multiple projects and is constantly playing catch-up which is just not possible. The ONLY solution for him is to pause production of everything except Seawitch pfs, complete all pre-paid customers based on the list posted on this thread (and any found paperwork), then like CPR does now do a run of 20 or so items (no pre-paids), sell those and then rotate through other items as needed.
I have always been excited about reproduction items in the pinball hobby, in the 'old days' we were cutting materials on band saws and printing artwork stickers on our home inkjet printers. The CNCs, 3-D and inkjet printers, and scanners of today are amazing, but I really feel the pre-paid business model just causes headaches for John and everyone else.
My 2 cents...
