M3 Or Supercard Lite and why?

Ok, I'm sorry for bothering you guys and this may seem kinda n00bish. Buts DS homebrew is very confusing choosing which, well, at least for me. I heard one site saying that homebrew doesnt work for the Red DS.. is that true??

Now back to the topic. I'm trying to decide which to get, an M3 or a Supercard because I know some people say super card is better, others say both are good, and some others say M3 is better. I want to know which I should get.
As long as they can:
-Play DS Roms
-Play GBA/SNES Roms.
-Play Homebrew Games and Homebrew Apps
-DONT damage my DS in any way.

Oh, and BTW, i have a normal DS, not a DS lite.
Also, do any of them come bundles with a Memory Card and/or card reader?

m3 has better support for GBA. both m3 and supercard can play ds nearly flawlessly.

though, there is barely any snes support for both.

i got the m3 because i wanted to play my gba games without having to remove cartridges all the time... <.<;;

supercard is much cheaper though.

thats all i know. someone correct me if i stated something inaccurately

I bought the M3 because of the overall compatibility plus it's uber easy to put roms on it thanks to the game manager.
If you do get a M3, make sure to update the firmware (I got the update at ds-scene.net) and this link: http://m3wiki.com/index.php?title=M3_NDS_roms tells you what settings to use with the game manager.
