I was in the same boat not that long ago - my A7D was as long over-due as your housing! Anyway, I sent it in Aquatica and they did an amazing job! They even replaced the somewhat scratched back LCD window! My housing came back looking, and working, like brand new. Definitely worth it for me!
As usual, I'm humbled by the images that get posted here! While against my personality, I'm going to knowingly break the rule as well! I'm posting two of my favourite images from 2014.
The first is an image from a cave diving trip to Tulum back in March. The image was made with one strobe, fired with a 15' extension cord so as to remove me (the photographer) from the image as much as possible (didn't need to slave it off another strobe). It was taken in a passage called "River Run" where a layer of freshwater sits on top of the infiltrating seawater. It is a magical experience diving this passage, and I hope the image offers some sense of it.
The second image was made at Whytecliff Park, a little closer to home, and a popular Vancouver, BC dive site. The site is located on a fiord and as such, has a steeply sloping wall that starts in 20-30' and plunges down to over 700'. The cloud sponges, the main subject of the image, start at about 100' and are a favourite with technical divers. This image is actually the start of a little project to shoot the sponges with tech divers... if we ever get our winter vis!
