I recently got one of these myself but afer buying I found this Canon S3 v. Sony DSC-H5 comparison which might be useful to others
Also this is the best UK price I have seen for the Canon S3 £247.99 inc. VAT and delivery is very good....don;t byu on the high street as you can pay in the region of £400!!! cannot vouch for this e-tailer personally so woulc suggest checking for shopper reviews...
hoep this is useful to others! :G
