Which Flashcard Should I Buy For Dsi Firmware 1.4?

Ok so I have a R4i card but I read somewhere that all the people that own a R4i card must buy another one that is upgradable in order to play again.
So my question is:Which card should I buy that is able to play on 1.4?Thank you.

Well, all flashcards are blocked right now but the M3 zero team are working hard I think.

don't buy one just yet, wait until a few flashcards can get around the block.

I bet the acekard team is working overtime when that update come up XD

if you have an acekard there's a fix at gbatemp now
