I went to the camera store and took a look at the Canons and Nikon's last night. I walked away with some serious gear lust for the Canon D-40 and a lot more questions than answers.

you gotta be thinking system, though, camera and housing. I think you really want a small housing so you can swim: olympus, seatool, hugyfot. Oly is most affordable.
I get both my housings, 3 camera bodies (410, 330, E1), dome port, macro port, ring flash, and a bunch of lenses, all into 1 (heavy) backpack. I regularly take two rigs in the water with me.
iThe Olympus dome port for that 8mm lens is $1,000, but I see that INON makes something similar for about 40% less. Any input on the INON dome ports? I was happy with my previous INON wide angle lens and dome adapter, but not sure how wel their domes will work on someone elses housing.
I think that athena makes the glass for the oly dome, the inon dome, and the athena dome. I'm not 100% certain of the inon... but if it's the same diameter, it's the same glass.
I just got back from another photo store and they had the camera, but not the 8mm lens, in stock. The camera DID have live view. I'll also add that this thing is TINY. I can imagine that even in the housing it would be no bigger than my old 5050 setup.
it's a little bigger than the 5050, but pretty close.
Any pictures of how big your E330 system is in someones hands? I'm assuming the E-410 would be smaller.
not in hands, but:

be sure the high ISO noise of the Olympus is acceptable for your needs
I never go over 100 asa anyway.
I was also wondering what the big difference was between the 14-42 and the 14-45?
Size. The new one is really small, 190 grams and 65.5 x 61mm, it's like an aspirin bottle. The old one is 285 grams and 71.0 x 86.5 mm
Oly actually makes or made 4 lenses in this range, it's a good working range and deserves some choices. They quit making the old 14-45. There is also the 14-54 f2.8, and the 12-60 f2.8. The 14-54 is the old E1 kit lens, it's their mid grade quality, and it's weather sealed. The 12-60 is also mid grade, sealed, and has a fast swd motor, it's basically the E3 kit lens. Prices jump from around $100 for the basic kit lenses, to around 400-500 for the 14-54 and I think up close to a grand for the 12-60, not sure.
They will also make a top grade 12-35 f2.0, it's not out yet. it should really rock. With f2.0 and image stabilization in body, you won't need to worry about noise, you'll never go to high iso. At least on land. I've hand-held the E510 at up to one second with acceptable results. f2.0 and one second exposures, who needs iso.

But the 14-42 in the water? not thrilling to me, honestly. Some use that range, it's nice for fish portraits and faces, but I like going wide or macro.
Oly has announced that they'll make a less expensive ultra wide (weitwinkel) zoom, too. Might be something for you to wait for rather than the 8mm.
