Nex7 repair costs?
This may very likely be damage beyond repair. If there is corrosion or other effects from the water on mechanics and electronics it is very likely that repair is not feasible option. Even if faulty modules are replaced in some short timeframe other modules may die or defect due to continuing corrosion effects.
Note that NEX-7 is about as complex and delicate of an instrument as it can get to fit the sorts of capabilities it has in the size of the camera it is. So maltreatment like water spills likely spells dead. It should have been pretty massive spill as the camera is relatively well protected without being water resistant, so things like light drizzle or some drops of water are unlikely to cause it damage.
