Canon SD900, got one and am more impressed with each passing week I shoot with it.
It has the abilty to shoot low light at 3200 iso, a bit grainy but you can get the extremely low light shot off without a flash. It has little noise at 400 iso. There are many many shooting modes including manual. 0.5 sec lag time when shutter button is pushed, less than 1.5 sec start up lag from off. Anti-shake and 30fps 680X420 MPG videos. This is the Cadillac of the Digital Elph series.....
$370 is the lowest list price. Get a 1GB SD card for this one and it will store 247 shots at the highest resolution.
