I would suggest Canon Powershot S10 if you are not EXACTLY on the market for
a big zoom. But the S10 has this nice panorama feature that allows you to
have pictures as big as you'd like.
The single most annoying result of digital cams is noise in the pictures,
and the S10 is 99,9% noise free. Besides, the S10 has excellent color
rendering in low light, something you are going to like. It's small enough
to have it always with you.
The prints from 2.1 mpix can go up to A4, depending on the printer you use
it's going to cost you plenty if it is a good one.
You can go to
www.folio.dk/pakkeriet to look at some pictures taken mostly
at low light.
S10 is better than Fuji 2800, without the zoom, and smaller. and it is
better than Ixus, and bigger than it but still pocketable.
Good luck
