ANY New Machine with surface mount parts on boards. When you have to spend hundreds of dollars to make a dollar repair I just don't see the logic of owning new machines. On top of that wait until companies no longer sell replacement boards and then enjoy your $10,000 paperweight.
I actually feel sorry for people buying these machines thinking all will be OK down the road! A buddy of mine that does pinball repairs full time feels the same way about the "new stuff". Even some of the 1990's stuff can be tough to get certain parts for so who wants to spend nearly $10,000 for a machine that might not be able to be repaired 5 years down the road?
