What equipment to buy for taking crispy and nice underwater pictures without investing an excessive amount of money for a DSLR (reflex) camera with expensive housing and strobes ? I'm quite demanding in terms of camera performance; ...I ended up buying a G9 camera with the Ikelite housing and one Inon strobe.
The G9 is the high end compact camera from Canon, the main advantage of the camera is that it takes RAW's pictures. The Inon strobe offers lots of power in a small volume. The Inon strobe is triggered by an optical fiber that propagates the camera flash light to the strobe photosensor. There's a good explanation here. The ikelite housing is very robust. The total cost of my setup is 2600 USD.
I recommend this equipment if you are looking for a photography solution that is less expensive than a SLR but still takes good pictures. Unless you have the money to buy a nice DSLR like a Canon 5D Mark II with housing and two strobes, this solution is a good trade-off. If you have spare money, buy 2 strobes instead of 1.
Since I'm swiss, I bought the items from Switzerland: the G9 from www.toppreise.ch ; the Ikelite housing from www.bhphotovideo.com , and the Inon strobe from Yuzo in Japan www.uwdigitalcamera.com . I spent in total 2685CHF (including shipping).
