Memory Lane is not that rare, and for that price ($3000), I'd need a truck to move all three machines. That is a bit rich.
An 8/10 Memory Lane would fetch $1000 - $1300 reconditioned.
"OK" is a bit vague - need to take into account the possibility of backglass peeling near the channel, corrosion on the MPU and any rust etc on the moving parts. Stern parts (plungers and flipper kits) are harder to source, but I have assembled a list of parts that you can buy to rebuild the flippers (Galaxy or Meteor thread).
From the description, I would not offer more than $750. Start at $600.
Definitely not a "rare" machine, and if it was, it is nowhere near $3000.
