*backing up* 😀
Here’s what a mate sent me when I asked him:
few links for you.
This is the manufacturer of the card.

Go here for the card. You can buy it in various guises but I use DSTT. R4 has had some issues. I recommend DSTT Without Retail Package. You can buy from here packaged with Micro SD card but it may be cheaper to buy them from ebuyer. Check both. Beware of some other suppliers. There are at least 6 copies in the market of the DSTT and they don’t work. I know I got 2!! The cards I got from these guys were genuine.

Go here for the memory chips (4GB Max). You don’t need a reader for every chip so if buying more, choose one without reader but no bigger than 4GB.
