After much research and price comparisons, I finally took the plunge and have ordered my new camera this morning.
It's the Canon Powershot S3 IS. Included was a 1GB SD card, a Canon soft case, a 21 in 1 card reader and delivery. Total price was $578.38.
The cheapest instore price I could find was $640 for the camera only, so I'm rather chuffed at getting this deal.
I bought from Digital Cameras Online.
It should be here by the end of the week.
