If you only want to play DS games, you can't go wrong with an Acekard 2i. The only difference between the 2 and 2i is that the 2i supports DSi systems (including XL) as well as the originals and lite. It's one of the cheapest, and one of the most compatible.
If you want extra features like cheat support, real-time saves (effectively save states), a media player, and single-card SNES and GBA loading, you'll want a Supercard DSTWO. It's considerably more expensive, but it's the most powerful card on the market at the moment. It blows everything out of the water, including the CycloDS.
As for SD cards, you definitely don't want to buy the SD in a bundle with the flash card. 99% of the time, you end up with a Class 2 Sandisk or Kingston, which are absolute shit (pardon my French). You're best off buying a Class 6 micro SDHC card from either Transcend or A-Data off Newegg or a similar store. Both brands are highly rated, and I've had personal success with A-Data, while I'm pretty sure Milady had similar results with a Transcend. Don't bother with a Class 10 card, as most are either a) false hype or b) using the SD 3.0 specification, which very few devices currently support. And I'm pretty sure no flash cards support SD 3.0 yet.
