Big writeup on the
Canon G10 (I've skipped to page 24 - Conculsion)
www.dpreview.com/reviews/canong10/24You're looking at just over $600, and another $400 for underwater housing, if that's your thing.
www.shopbot.com.au/default.asp?orderby=&p1=&p2=&kw=canon+g10&position=searchYou may want to consider a
Nikon P6000 instead. I've just bought one but haven't used enough to comment, apart from
any compact feels very schit after a SLR. This camera includes GPS tagging, but I've yet to see it actually work. Video is quite good, using it a lot. It has replaced my video camera. The camera can upload to Nikon's version of Flickr, straight from the camera.
Comparisions between G10 and P6000:

DSLR for $500. Dunno about lenses though. Speaking of which don't fret over megapixels, 6 is ample. Just remember HD television is about 2 megapixels.
I recently picked up a fixed 55mm lens for $200 brand new and it is sharper than what my camera can actually handle. BTW dpreview now has in-depth lens reviews.
... but I digress.
What are you going to use the camera for? There are guys on this forum that are camera mad and I'm sure this thread will eventually be very, very long
