At least you didn't let the salt water bath for your camera spoil your mood.
After flooding my Ikelite housing by not latching the back, I grabbed my video camera and had a little fun with my Nikon D700 on the reef.
If I was going to take my DSLR swimming I would want to put insurance on it. DAN seems to have a particularly good gear policy that looks covers anything except throwing it overboard or dropping it while diving. It certainly names flooding, theft, and airline mischief.
I think my immediate path forward is another compact camera. I'd really like to take the DSLR swimming, but I think right now that's overkill and overcomplication for where I'm at.
There is a little debate on Sony vs Canon, although I think from Backscatters articles and videos that either would serve me well. Video isn't really my thing underwater other than small bits. It seems like what I see in my mind when I hit record and what shows up on the memory card are from different universes. I see smooth, well framed footage... what shows up on the memory card looks more like a GoPro strapped to a fin. Reality is somewhere in between, but the footage isn't good for much other than reminding me of the good time I had.
On the bright side, the Canon is only a $500 fee when you flood one. Sony is still commanding around $1K for a used one.
