We bought a Canon S400 about a year and a half ago and recently it started getting an error when we started it up – “Memory Card Error” is what the screen read. After researching on the Internet a while I found that this was a common problem with this model (read the hundreds of reviews with the same issue). I contacted Canon and found that they were willing to repair it for between $150-300. I decided to spend that money on a new Casio Elixim Z750 – no more Canon product for our family for a while after this experience.
