I had all eight done just over a year ago. $600 in labor. My advice is when digging in that far you're money ahead to do them all especially knowing the others aren't far behind. I had to put mine on the credit card but it was that or pay again throwing labor costs away. I also went with Ford remans and they come with a two year warranty. I understand working on an underfunded budget (I'm a teacher!) but my truck wasn't going to run right otherwise. Good luck. I feel your pain.
