Pictures.

Seriously, people can get hung up on condition. For instance, anytime I hear 'HUO', "mint" or anything similar, I run the other way. Those translate into "I want more money than this machine should ever be worth". Better to just take some good pictures, and let people ask for additional pictures if needed.

Players machine= serious playfield wear, cracked plastics, credit dot

Shopped= rubbers replaced within last year, playfield given wipe with Novus two right before photos taken for craigslist, new balls

HUO= I dont see any lock down bar holes, must be HUO

To be serious, I find just be as descriptive and honest as possible when selling a machine. Tell the buyer all the things you have worked on or fixed. Point out any playfield wear, cabinet dings, or cracked plastics. Provide through high res pics so they can see all of that if they are not local. Provide a history of where the machine has been to the best of your knowledge. I know you hate to point out every flaw so make sure you accentuate the good as well. I like to give a list of all the positives first -- Like I just redid all of the GI connectors, the playfield is diamond plate with no wear, I just replaced this expensive hard to find ramp-- then hit them with the bad.

Honesty is always the best policy.

Subjective at best.....more often just plain bull, especially ebay.
