I have a XR7 playfield on the lower and upper field. Compared to the standard lacquer playfield that I had in another one previously, the difference in colors is huge. The white on mine has zero yellowing. I’d be interested in knowing the value too. Not that I’d ever sell mine. Just curious. I’d say 8k would not be out of line for a collector who really wants one of these. I’ve seen them listed for around this price in the last 2 years

I knew I could eventually swap out my crappy yellowed playfield in my old Banzai. I went for a beautiful original xr7 machine and sold off the other game. For me it’s the collectibility aspect. I also agree repro playfields play a bit funky
