I wouldn't get the Sony H1
lots of people complained about CA from this camera over the net... thought it does looks cool and it has a nice IS feature..
I like Canon cameras
I'm biased toward them.. so either S1 or S2 are all pretty good IMO
but I have to say, the F717 is a nice camera too. It feels pretty solid and durable compared to the Canon S1/S2, and has nice features too.
just my 2cents
