Make sure it is compatible with latest DSi firmware - 1.4:
EG: R4i Revolution SDHC for DSi / DS Lite
Compatible with both Nintendo DSi and DS Lite
Now compatible with DSi Firmware 1.4!
gadgetgear an Aussie seller via Hong Kong has the R4i chip and an 8GB micro SD card for $95 with free shipping or $45 stand alone (no sd card). Just use Google to compare buying here vs Bali...
Also don't let the unit automatically check for firmware updates either - as Nintendo will create new firmware bypassing the R4 function at some point...
