Shopped
My definition would be a playfield teardown and clean. Mainly a cosmetic job - replace globes, rubbers and any broken small parts like plastic posts. It would not include broken parts such as slingshots and ramps. Typically 10 -20 hours
Reconditioned
As well as the "shopped" work - All mechanisms under the playfield are rebuilt. All coil sleeves replaced. New flipper kits installed. All boards upgraded and repaired. Sometimes, broken ramps and slingshot plastics are replaced. Typically 20 - 30 hours
Restored
As well as the "Shopped + reconditioned" work - Every single moving part is rebuilt, cleaned and polished. The machine is virtually stripped of every part, and each individual part is cleaned / polished or replaced. New plastics sets and/or ramps are installed. Anything that can be bought such as plastic and metal posts, flipper bats, screws, nuts are installed on the playfield. Cabinet hardware is replaced or polished. Cabinet may be painted.
Typically 50 - 100 hours.
