I use a 4 GB SDHC Sandisk Ultra III, like Stillbear I keep my recording times low to less then 30 minutes. When the recordings are large they are difficult to find specific points of interest. I use Humviewer to look at the recordings on my computer and can scroll through them pretty quick.
Also I have 2 SDHC chips which I trade out each trip and I have a 1 GB chip (smallest I could find locally) which I use for updating the software on my unit.
