EDITED FOR CLARIFICATION: LOW BATTERY MEANT TIME CONSTRAINTS. Having used them back in the day, it wouldn't be surprising if the 2GB Kingston JPN is still among the best in overall performance. Unfortunately, 2GB no longer cuts it for me, especially since I'll likely be abusing the features of a newly purchased Supercard DSTWO. I currently have a Sandisk 8GB Class 4 card, hopefully that can work just fine for the time being, but I'd like to know which Micro SDHC cards are the best of the best. Hopefully I'll be able to purchase one.
