1 year factory warranty on all boards, with a no questions asked replacement in the event the board fails for any reason.
Know your market. 
Socketed ICs, Through hole transistors, JJP at least has considered future repairs. I guess their market is a little different, they are really targeting the pinball enthusist/collectors market.
Where Stern, whilst telling people they are building for the home collector they are cutting costs and trying to get as many games as they can out the door, unfortunately leaving people unhappy, ultimately losing current and potential long term customers in the process.
Their games have seemed to be going towards the 'Costco' style for a few years, but AC/DC has been a real turnaround especially the Premium and LEs, just a shame about the quality, fingers crossed they will be reliable for many years to come we have to hope Stern have not cut costs on electronic components as well.
