I've thought about an S95, S100, S110, G12, G15, G16 or G1 X and the compatible Canon housing to replace my SD600 for the rare underwater excursion, with the added ability to do HD video. I really didn't bring it up because I'm planning on buying an Ikelite or anything, I was just more curious than anything else about others' experiences on the forum.
Hi KyleSTL, Ok, understood, but in your original Post, you mentioned DSLR, if your looking at Housing say the S95, then it's a whole different ballgame and much cheaper.
I House an S95 myself, takes quite good Images, takes Video, the Main drawback to Point & Shoots for Underwater Imaging, is the delay between Pushing the shutter & the Camera taking the Image, if you can work around that then your set.
The Housing I use for the S95 is the Fisheye S95, retails for around $700.
Add a single strobe set up, in my case the Inon D2000, $600, The D2000 has the advantage of being able to use it both as a Flash for Stills, or as a Video Light.
Then you have to add the Port, say $500, and your good to go for around $2000 (added strobe arm & baseplate/Handles).
