Sound board gone: $300
MPU gone: $220 (no ASIC, CPU, ROM to transfer over)
Right Ramp: $160 (have to get shipped from pinball spare parts)
So, that's $550 off a quick eyeball. The crane is gone, missing light boards, flipper mechs wouldn't be hard to find, but another $100 in parts. Plastics for JD are impossible to find, probably $150 if you do. I'd estimate $1k-1200 in parts by the time it is all done, plus a year or two of waiting on some of it.
