Hi all! I'm looking for a new compact digital camera and i will probably go for one of the following. Could you please advise me on which I should prefer? Thank you in advance! 1.Canon Ixus 860 IS (Canon PowerShot SD870 IS) 2.Canon Ixus 870 IS (Canon PowerShot SD880 IS) 2.Panasonic DMC-FX37 3.Sony CyberShot DSC-W210 Probably the 2nd one is the successor of the 1st one but does it worth it value? What about the others? Thank you!
