The name of the game for these container importers is turnover. It makes no sense to trade dollars for dollars with the seller spending $600 on a machine with parts and labour, to only get an extra $600 back. If the sellers did this on every machine, there would be a backlog for months, and everyone would be waiting for their machine to be ready. Plus the fact that most people want their machines prepared a certain way. Its hard enough for these sellers to cashflow so many machines to strat with, let alone adding an extra $600 per machine to have sitting on the floor. That would add up to alot of money for the amount of games they are holding.

Also, most buyers dont want to pay someone a minimum of 25 hrs labour @$25 per hour ($600 plus) to clean a machine, rerubber n reglobe when we can do it ourselves.
Mark C for example, always provides a honest report card for every machine. All machines are plugged in, powered up, fault tested via the games own menu on start up, a realistic deskription of the playfield with photos is provided etc, and within 5 minutes u can tell if its a real good machine or not. I ask for real good examples to add to my collection as keepers. Therefore, I know exactly what I am getting before it even arrives. No luck involved, its just good management by both seller n buyer.

Most sellers are happy to move them out the door without even having to touch a bulb. The hardest thing for them to do is to plug it in, do a report card, and determine a fair price for the machine "as is".  Its really the best deal for both seller and buyer. Its worked for me alot.
