Best ds card to buy???

Hi,
My kids have a ds card (firecard) each which they've had for some years now and which has no recent updates (2 years since last one) so Im looking to buy them a new one each.Looked around the web abit and with so many to choose from I was wondering if anyone could recommend one.
They are for dslites if that makes a difference in choosing one.
Any help will be greatfully welcome.

You can't go wrong with AceKard 2i (2.1) or M3, mate.
I hear Supercard is good too.

Yep , Acekard , M3 ,Supercard
