Just picked up a Patriot brand 4gb SDHC card as a back up for my 1D MKII for $19.99 + tax, a great deal. Orginal price was $27.99.
Frys also have a A-Data 4GB for $19.99 as well but I've read that Patriot is a little faster but since I've been using Patriot RAM in my PC, I went with it.
Just want to pass it along.
