Hey sorry I'm replying so late...
GO FOR IT!!!! I use a Canon Powershot S3 IS and can say it's a very nice camera
It's light on batteries and also can get excellent quality photos
... you just need to figure out the settings and bang you got a excellent buy
It's a very easy camera to use since it can zoom in a LOT and has macro and super macro on it
Going to find you a few nice shots I took with mine
