I have no real desire to have BIN... im also not a big fan of STERN machines.
I get a lot more pleasure picking up a destined for landfill wreck and turning it into a factory showroom product... takes a couple of years but i really do enjoy the drawn out process.
But... were i to buy BIN, id be more inclined to buy from Jack or a small fitout like Retropinball. I wouldnt buy STERN, same as i wouldnt buy PLAYMATIC or RECEL
