I mean, in fairness, repairs are a lot easier and more of a sure thing now too. Bad MPU or driver? You know exactly what your ceiling on the repair is going to be because aftermarket boards are freely available. Isn't like the past where you might be stuck repairing battery damaged boards that would never be reliable because spares didn't exist, or where there were known failure points of a given board set so any game running it was a time bomb with no repair path except more of the same high failure rate parts. There are very few projects today that aren't repairable with off the shelf parts, about the only thing that can truly kill a machine is non-reproduced game specific parts broken/missing or a totally trashed playfield... There were a lot more items that would turn it into a parts game if they were missing/busted a decade or two ago.
