Best brand of SD card for camera?

[ka jowct]

I have maybe five Sandisk and one Kingston. Three or four of them are 1GB cards that are 4-5 years old. The only problem I've had with a Sandisk card so far is losing one. It's probably here somewhere, but I cannot find it, nor can I remember enough about why I swapped it out of the camera to figure out where to start looking. Nice 4GB SD-HC card, in use since April 2009.
