I ended up getting the Ikelite housing. I will do a follow-up report in a couple of days after a using the camera and housing in Bonaire last week here: http://www.scubaboard.com/forums/canon-corner/441806-canon-sx-260-hs-ikelite-housing.html
I was going to suggest getting the SX230 or SX220 and the WP-DC42. The combination is probably cheaper than the ikelite housing.
There isn't really anything you can gain from the SX260. Unless you put the camera on a heavy duty tripod, no one has the hands to hold it steady at 20X zoom
Let us know how the housing is
