I use a Fantasea housing, which I like a lot because it has a dual gasket and the buttons on the back are clearly marked, making it easier to use (in my opinion). I do not use strobes now, maybe someday, but not being a serious or dedicated photographer, I am not prepared to deal with the hassle, extra weight and size of the kit. RAW is easy to process, and you can correct a lot of amateur photographer errors relatively easily, and even if you don't do a great job in the post editing process, the photos will still likely look better than the scene you actually saw at depth. There are many programs available to process RAW, and many of them are free downloads. You can get a lot of helpful advice from some really good underwater photographers on SB. Just ask for help, and you will get it.
