Quoted from Rush1169:
Let's say Dr Who is $2,800 typically to purchase (freight included). For commercial operation, I've found that these 20+ year old games *require* a full-blown tear-down shopping (30+ hours), some new parts, I do premium LEDs, often a new DMD, legs, levelers, flippers, etc. Roughly $800 to $1,000 to fully rehab. So, I'm starting out @ $3,800 for Dr Who, but it plays like a dream (that's important). Figure a $2,500 residual value whenever that day comes. So, the real cost of this game is $1,300 ($3,800 - $2,500)
Honestly for $2,800 you should be able to find a "plug-n-play Dr. Who.......so $300 (real cost)....maybe $500.
