Earlier machines (pre1995) were a bit problematic. The later ones are much better. They sometimes have little problems here and there (we've had trouble with hyd pressure switches, coolant pumps and sometimes tool measurers sticking. Overall they are a good buy. They seem to be built stronger than some of the Japanese machines. Of course you can still get a bad one like with anything. Would be hard to go past one (for a middle range machine) in my opinion. There are better and there are worse around.
