16GB SDHC memory card class 6

[calvet]

I'm looking for a 16GB SDHC memory card class 6, preferably San Disk, Panasonic, Toshiba, ATP, Apacer or PQ brands. I bought a generic card online from China and it wasn't compatible with either my Panasonic still camera or my JVC video camera.
I've seen them in sale ads for ~$23 or so in the past.
Thanks for your help,
Richard
