The EZ-Flash IV takes mini SD cards (I'll admit that's a little odd) and generally works just peachy.

I have observed – and this might be corroborated with others – that it seems to have an unusually high power draw; specifically, when I use it on a GBA SP, the power light tends to blink from green to red with alarming frequency. Perhaps this is related.
