Query: Best memory card on the market

I have over 20 memory cards (CF, SD, xD, etc.) for PDAs, phones, digital cameras, etc. and this Sandisk 60x CF card is by far the fastest card I have ever used. I am using it for an 8MP Canon Digital Rebel XT SLR camera. Amazing little machine: I no longer have to wait for shots to get stored before moving to the next, it lets me take advantage of the continuous shoot mode (14 pics in 5 sec), I can now record high resolution video for up to 20 minutes in MPEG mode, and photo recall is almost instantaneous. The 2GB card is not as fast (slower interface) and much more expensive, so this card is the best compromise for speed, size, and value.Fyi - I tried the Lexar 80x cards but their Write Acceleration technology does not work for a lot of cameras (Canon, for example) and some PDAs (select HPs), rendering them average cards for most uses. Other reviewers cite websites where you can check compatibility and speed comparisons across all cards.
