No problem. Yes, the E900 is a nice camera too that offers good high ISO performance as-well. Not quite as good as the F30 but still a pretty good ISO800, plus it has RAW as you state. I suggest you check out
www.inonamerica.com too, if youre serious about underwater shooting INON makes great strobes and have some good lenses too (macro, wide angle) that fit the F30 and a mount thats specific for the F30 (also see this thread here:
http://www.scubaboard.com/showthread.php?t=159415). In fact, I see many posts here by users of such P&S cams such as Olympus Sp-350 and Canon S80, Fuji E900 etc.. that use such setups (Inon strobes, lenses, etc.) and they produce incredible images, very very comparable to DSLR images and in my opinion just as good. That said its not cheap but still significantly less than a DSLR setup still. I honestly, think the difference between DSLR's and P&S's is much more significant topside and less underwater since there are plenty of accesories for P&S cams (even the F30) you do have the equipment to be able to produce striking results as I see posted here often. Also, no its not fully manual, but remember if you shoot in Aperture priority mode and set the aperute to say f5 (the sweet spot of this lens or any other aperture you please) and use +/-EV adjustments, you can make the camera adjust the shutter speed in -1/3EV incriments, getting you very close to fully manual anyways (or the opposite, pick a shutter say 1/125 and use EV to adjust cams aperture). Though, the F30 is not a perfect camera by any means (no cam is really) and I woudlnt want to give you an unfair view, the most major problem it has is Purple Fringing which is significant at the wide open aperture (f2.8), but the easy solution to this is shooting at an aperture of f5, which completely takes care of that problem. Also, the F30 can overexpose in bright and contrasty scenes outdoors (probably not a factor underwater) in those cases I recommend using -1/3 EV on Multi (pattern) metering and also using Average for landscape scenes is great. Also, in shade and overcast situations, the Auto WB is a little too blue for my liking, I always use Shade WB in these cases for a warmer color. Just some tips for you if you eventually get the camera and all the shortcomings of the camera can be corrected with a little knowledge (without even having to resort to post-processing at all). What I like about the F30 is that, it has really enabled me to understand digital photography a lot better (Aperture, EV adjustments, metering, etc..) and got me intersted in going fully manual (a DSLR - for land), I feel much more comfortable now using friends DSLR's.
EDIT: PS. One last tip

, the LCD on default is way too bright, when reviewing your pics many look quite overexposed but are in fact fine its just the overly bright LCD, so set the LCD brightness to -2 for an accurate depiction of what the camera records. That was my last tip
