Mike are you okay with horizontal modifications done within the warranty period? Would you consider factory supplying one of these more elaborate game boards in the future? Seems like a portion of the market are tuned into the fact the 60-1 does not hit the mark - or is the intended market still fine with a 60-1?
The machine is factory made for vertical or horizontal installations. There is no warranty issue at all if swapped.
The other game boards are simply not available within China or I would certainly offer them.
