I'm wondering if you read the review I posted the link to. It states that iso 400 for the canon is perfectly usable and even 800 is OK for small prints. It depends what way you like to look at your shots. If you print them at 4x6 (R4) you probably won't be able to tell the difference between iso 80 and iso 400. And don't forget the IS means that you will have less need to step up to the higher iso values anyway. I cannot stress enough how good the IS is.
I'm not trying to put you off the Fuji (my previous 2 cameras were fuji - my S602zoom is probably my all time fave DC), but here is a quote from the conclusion of the F30 dpreview:
"On the downside the F30 is not as impressive on bright sunny days as it is indoors or at night; sure, the sharpness and low noise are still there, but the tone curve often produces images that lack highlight or shadow detail, yet can look a bit flat. You'll get some amazing results if you know your way around Photoshop (or similar), but I often (though by no means always) found the 'out of camera' results slightly disappointing. Add to this the tendency to over expose and you've got a camera that really needs to be used by someone who knows what they're doing to get the most out of it."
The xd cards used in the Fuji also annoys me cos I already have about a dozen sd cards and don't want to have to buy new xd ones.
For me the wide angle and the IS combined with the most usable high iso performance from canon yet, made the 850IS the right choice, though I agonised over it for weeks. It's a point and shoot - I don't want to have spend my time adjusting exposure compensation and the like to get a good shot outdoors.
As for imports - they are usually 4-600 bucks cheaper and you get no official warranty. 7 days to return to the shop if there's a problem and then a 1 year warranty WITH THE SHOP, not with the manufacturer. They will usually charge for parts for not labour. Your english manual will probably also be a photocopy / printed pdf file.
The canons are named differently if they are imports. I bought the import, so although it is an Ixus 850IS, it is called an Ixy 900IS for the Japanese market. If you want an import you may have to ask for it specifically.
There are several shops in Wanchai Computer Centre or 298 Computer Centre who will not rip you off and are good to deal with. Most offer pretty much the same prices. Be careful about buying an extra battery / memory card - you can usually get these cheaper somewhere else (especially the mem cards).
Pls let us know what you decide to go with.
