I would like to buy a new one if possible.
Not sure if you had noticed, but the F828 has a major problem with purple fringing (purple ring around white lights)... more so than the other 8 megapix competitors. F717 should have less, since it's 5 megapix. Plus F717 should be able to get at SGD900 (friend in China told me it's selling there for 4500 RMB), whereas F828 is selling for SGD1470 (exclude GST) at Sim Lim.
Would like to get the F717 to play around with, before upgrading to digital SLR a few years down the road.
