CheddarChick:I also put a 1 gig card Sandisk and have had no problems with freeze up. It also has manual white balance. It is very easy to maintain also and the help I have gotten from Sealife has been great. I know the battery life is an issue but I bought a second battery for $14.00 with shipping. I took 87 pictures on a 1+ hour dive and never shut it off. I kept the display on at all times. I know Sealife said they are working on a new battery as we speak. I got my whole setup for $617.00 and at this time as a novice I wouldn't change it. It's sometime hard to remember that you are diving to dive and taking pictures is a pleasant side effect.
After tallying all the research I've done (internet, user stories, spec sheets, personal experiences with several cameras), I would recommend you do not get the Sealife. It appears that its failure rate is about 30-50%, and Canon/Nikon/Olympus have better optics and user-interfaces.
For less money you can get a better Canon, Olympus, etc, & house it. Just an opinion, but so far the reported surprise failure rate of properly housed Canons in the field is around 0%....
