Experience with Olympus C5060 and PT-20 anyone?

Hello !

I am in the process of looking for a new UW-Camera (digital).
Before I used a Olympus C5050 with a PT-015 housing
and I was very satisfied with the result
- even without an external strobe (thanks to Photoshop...)

Today I tested the new C5060 and was impressed
(faster autofocus, wide angle and quieter zooming).
Since the C5060 uses LiIon-batteries I am wondering if anyone
uses this combination.
My first UW-camera was a SONY DSC-P5 with the SONY housing
and that was very bad: the housing began fogging just after 10 minutes
into the dive - I think because of the LiIon-batteries the SONY uses
- they get very hot... 8((

With the C5050 I used "regular" rechargable AA-type batteries
and that worked great:two or three dives with one set of batteries
and no fogging of the housing.

Now I fear that the C5060 (or its LiIon-batteries to be more exact) might
fog the housing also.

Anyone out there who can tell me his/her experience
(handling under water/fogging/
how many pictures before the batteries need charging and so on)?

Also I´m very interested in hearing what kind of external strobes you use
with that combination and which settings you use with your camera and with your flash.

TIA
