trustworthy store to buy ds linker?

just got ripped off by consoleup.com so i need some advice where to buy a ds linker or something else to put games on a card.
I bought a 89 in 1 card on holiday it now says open fat error, i thought if i got a ds linker i could reload the card with ds roms (is this possible?)
i am lost when i look at all the sites so many cards which is the best?
any help please....:confused:

andy, i got an acekard 2 from dealextreme.com, just need a microsd card. acekard has an opensource os from their website. I've been extremely satisfied. Sorry you had such a bad experience.

i also get flash cards from dealextreme.It is quite reliable but shipping takes time.
