Query: Do not buy a Canon camera.

If you really are going to buy one .. try this search on Google first "Canon e18". Read the reports this returns.The dreaded e18 error affects cameras across the line and means they are pretty much dead (lens will not retract). Mine got the error a few days ago.Canon has evidence of hundreds of such errors but provides no information on their website.
