Query: It WAS a great camera...for a while

I bought my S400 in August 2003 and it was truly a wonderful camera until July 2005, when I started getting memory card errors. The error occurred no matter which of my 3 compact flash cards I used. Then the camera refused to work at all. Canon is willing to repair it for $150 plus shipping and tax, and I'm not certain that it's worthwhile to do this.Please think twice before purchasing this camera. The current 4 star rating does not accurately reflect the camera's performance after 18 months or so.
