People think pinball is so hot its melting planet earth but in reality everything is gone way up. Pinball is just another item that has skyrockted. Check the prices for wood ... have you checked up 3x. Exotic cars have jumped like 35%, you can't find Dodge Challenger Hellcat for less than 20k more than retail. Home prices are somewhere near the Moon.
There is basically NOTHING that isn't sky high. The country is dealing with a lot of inflation, shortages, slowdown due to parts and labor, its basically everything.
The country could be headed for a recession then who knows what is going to happen.
Right now isn't a good time to buy pinball or a new home. The stock market is sky high, not a good time to buy in.
If you're concerned about prices just wait it out, but if you need that game in your collection then pay up!
its your choice!
