UW case or just a simple UW camera ?

Hello guys,

I'm a newbie on this forum and I'm sure I'll find helpful people and infos !

It is now official: I'm considering passing my PADI Level 1 exams in Thailand so I will be on holidays and passing PADI as well.

At the moment, I still have my trustworthy Lumix LX3. I've been very happy with this camera so far.

Because of my recent interest in diving, I though it would be good to bring along a waterresistant camera since I would be happy to take underwater pictures.

At the moment, I am considering two options (please note that there is no UW case available for the LX3... : )

The Lumix DMC-FT3 or TS3:

Can go down to 12 meters deep (hum...really ?) and got this cool GPS feature...which comes very hand to know "where" the picture was actually taken !

I know this Lumix will not have a better image quality compared to my Lumix LX3 but I will be able to go underwater with it !

My only concern is knowing if I can REALLY dive down to 10 / 12 meters without killing the Lumix FT3 for good.

or...

The Canon S95:

which has a much better overall image quality and I can put the UW case when I want to dive:

Or so no GPS feature...but I'll live without it...not a deal breaker.

My questions regarding the S95: are the Canon UW cases rubbish (they are at least £ 185) ? Any good ? Should I invest in a real UW case instead (Ikelite for example) ?

Soooo...FT3 without UW case or S95 with UW case.

There will be a nice price difference but I'm open to any idea or feedback.

FYI, I'm not considering DSLR: I had one but too bulky...

Many thanks for your help.
