I think some of you guys have no idea how badly worn some of these machines can be. Water damage, rust, playfield wear, cabinet fade (9 times out of 10), missing parts, etc. The "beat" machines that are criticized for sale here would be above average for a container load.
I went in on a container load about 8 years ago, and I don't think I would try it again. Not to mention, the cost now is higher and it seems the selection is worse.
EDIT: Most of the machines I received from the container were sold to operators who could still make money on them. No way would most collectors have approved of their condition.
