Ikelite are just one manufacturer of underwater housings for cameras,
there are plenty others, some much better than Ikelite (IMO).

Have a look at http://www.digideep.com/ and http://www.wetpixel.com/
for lots of information & reviews of various housings, etc.

If you are in the UK, http://www.camerasunderwater.co.uk/ is a shop worth
a look.

Safe diving!
