Great Deal... Kingston 4GB microSDHC Class 4 w/2 Adapters Probably great for M3 Real or DSTT http://shop.kingston.com/PartsInfo.asp?ktc...o=SDC4/4GB-2ADP On the side note...I tried a 4GB A-data and had no luck. The M3 Freezes on me at different areas. I tried reformatting SEVERAL times: FAT with M3 REAL USB adapter - Tried this 3 times FAT32 with M3 REAL USB adapter - Tried this 3 times FAT with R4 USB Adapter - Tried this 3 times FAT32 with R4 USB Adapter - Tried this 3 times I cant' use the SD Adapter it comes with, my card readers won't pick it up. And each time I formatted, I used the panasonic SD formatter. What is the trick? Anybody had luck with 4GB cards? I really don't think it's the SD card.
