Hello, Recently bought a Canon SD800IS to replace a Canon SD450 (just wanted to get the IS and wider angle lense) to take on a trip to Japan. This is my first trip there and I intend to take an obscene amount of photos. I am, however petrified that I will have memory card problems, only because recently most of the cards I have used in the past have had an issue. I have used a Ritek 150x 2gb card that became completely unreadable or writeable after only a couple months. I have also used and Adata 4gb 150x card that is now only recognizable by my PDA so it has stayed there. I bought a 1gb 60x PQI card a couple weeks ago and I already got a memory card error from the new camera. I reseated it and it has worked, but now I don't trust it. Do any of the veteran SD card users have any recommendations for me? Price and value have always driven my purchases in the past, but this time around, I can't afford to lose any pictures. I can't spend too much money, but will definitely pay a premium if I am getting a reliable card (that is of course big enough and fast enough to take movies using my SD800IS). Thanks!
