There was problems with the bearings (I believe it was an oiling problem),
but that was resolved.  These are rather simple engines with a low thrust
rating... but yes, 4 engines will be more expensive than two if all things
are equal.  If they went with two engines (considered in initial design
stages) they would have to be alot more powerful for if you had an engine
failure you would loose 50% of  your power, whereas with 4 engines it is only
25% of your power.  Besides, the plane looks great with the 4 engine setup.
