Depends on what you're including.  

I spent a good bit more than that all-in, but I'm including the TracVision, BluRay & TVs, and other work like relocating the old VHF.  I also had some other work done at the same time, like replacing my spotlight control pad & relocating my gas fume detector - so it's hard to break out just the electronics part of the labor cost.   

Taking everything into account, you're probably not far off.
