Quoted from Highclasspinball:
Don't worry. I have a different business model.
First I have only one perfect quality level. There is no use for replacing a worn playfield with production seconds.
Whatever I did will be available as long as I have stock and will be rerun before I run out until any 3rd party licence expires.
And as preorder lists take a lot of time and are not very accurate i do not do them at all. This saves time...
With a capacity of 50 to 100 playfields daily I have enough room to react to demand increases and usually always stock at least 10 of each kind...
Oh wow so awesome. Thanks for the info!!
