I recently did the IPS LCD upgrade on my R&M. It's a fantastic upgrade to the stock LCD and makes for a much better viewing experience. The blacks are dark black, there is no washed out gray and the viewing angle is almost unlimited. I originally ordered from Amazon the LCD and controller and most of my research showed that ordering a similar item from China direct wasn't much cheaper. I finally heard back from a few distributors and it seems like, in large enough quantity, there can be a decent discount had. Price for screen and controller would likely be around $110-120 or something like that. I designed some brackets to mount this in R&M and am working on getting some feedback on a new set for ACNC and TNA. I don't know about the other Spooky games but happy to help figure it out.
Here are the brackets for R&M. The ones for ACNC and TNA are similar but modified to fit the different wood panel those games have instead of the metal. https://pinballmods.co/rick-morty-lcd-upgrade-ips-bracket?search=bracket
I posted a bunch more detail on the R&M club thread: https://pinside.com/pinball/forum/topic/aw-jeez-official-rick-and-morty-club/page/311#post-6430379
I also created a new abrasion resistant acrylic panel for R&M to replace the stock one that is there. I think the original is PETG and is about .06" whereas the acrylic is .12" and has much better clarity. Waiting for some feedback from the few samples I sent out but it seems like it could be a nice companion upgrade. This would likely be another $45 or so. ACNC and TNA might be a more difficult upgrade since the stock piece is glued/siliconed in. Haven't had anyone attempt to remove it yet and I'd probably need to get one in my hands to design the replacement to be exact.
Just looking to judge interest mainly on the LCD/controller. Probably need to order 25 or 50 pcs to get a significant discount. Delivery times would be pretty fast since it would be via DHL.
