What the best DS cart to buy??

Not sure if there is a post with this already but please point me in the right dir.I have A DSTTi and lots of the game are starting to not work straight away as we are starting to find out
so i guess which cart is easy to use?
which is the most popular

the best i think would be cyclods? correct me if i'm wrong and oh yeahh the acecard is pretty good =P

DSL: Cyclos, Edge, Acekard 2.1/i.
DSi: Acekard 2i, M3i Zero (I think that's the name). I've also heard that the SuperCard DSONEi is good.

i've got a M3 Real, perfekt pack so you can also play GBA games ^^
very conveniend!haven't had any problems :)

I completely agree, My brother has one and it has worked flawlessly
I don't particurally reccommend R4pro because i've had a little hassle with getting cheats to work,

CycloDS all the way... they rock.

DS Fire Cards are awesome, they work lika a charm
