best flash cards with microsd

hi everyone,
i dont often post but i need some sound advice pleasefirstly,
can anyone tell me the best card to use in the normal nintendo ds, i have been using the R4 v2 (a clone in know)with kingston 2gb micro sd and getting them from deal extreme/volume ratei have been having a few problems with the (cant access data - games freezing etc etc) only on a couple of newer gamesall i want is trouble free and hassle free gaming if there is such a thingand
secondlyif i get the new DSi which is the best to use in that ( ie which card/microsd)thank you so much in advancejo jo

CycloDS Evolution is the best DS/DSlite cart, Acekart 2i is the best DSi cart. Sandisk and Kingston are the best microSDs.

thank you very much
i will look into acquiring one or the othercheersjo jo

hi,can you point me in the right direction as to the cheapest place for the cyclods evolutionand will the acekart 2i card work in the ninetendo ds as well as the dsi or is there compatability issuesthx againjo jo

Acekard 2i will work in both I believe.
