Honestly it’s not that hard to accumulate donor pays for a classic Stern or Bally build. I’ve acquired all my quicksilver parts over the past 6 months casually watching eBay.

Going the classic route has advantages since there’s a large supply of salvaged mechs like drop targets out there. Electronic are either readily available on eBay or can be purchased new. Cabinets can be built from scratch and fitted with repro trim etc. Plus there’s a lot of knowledge out there on the early ss electronics and wiring to help if you get stuck.
