Help me rip off Nintendo

So I'm getting a DS, and I wanna know, what's better M3 or Supercard? Or is there some alternate? Some of my friends said M3 is the best I could get, and others think Supercard does the job as well. I'm sure Anonymous' collective knowledge can provide a helpful answer.

M3 & supercard both play most NDS games
but M3 has the added funtionality that their GBA support is better

and M3 got some extra features over the supercard

Ignore them and get either an M3 Simply DS or an R4 DS, which ever you can find cheaper. The are the EXACT same thing, firmware and hardware.

Whatever you do, don't get a G6. I got one of their Lite models, thinking to myself "how could I ever use more than 512mb?" (640k lol), and boy was I ever wrong.
