Thanks for all the great info. I think I want to buy the G11 so its a camera I can grow into. But I have no plans to buy a strobe, for now at least. I think since this is my first "big" dive (one month away diving) trip I want to have some underwater pictures. nothing special but ok. I already own a Nikon Coolpics S51 for above water, its small and take great shots. I will cancel the PADI course based on all your recommendations. But I will go with the Canon G11, with the Canon's plastic case. Any other housing just seems way to over price for my taste. Based off of user Broadreach I will just not focus too much on the shot and just run and gun (with the camera of course) and try to have fun. That's the point any way right!!.
Buy the way when diving what kind of retractable clip should I use to hold the camera? And should I jump in with it or just have boat crew person hand it to me after I am in?
Thanks guys,
