Flashcart Retailer!!

Is Neoconsole.com a reliable place to buy a R4 SDHC?

Maybe, but the problem isn't where you are buying your R4 SDHC, the problem is that you are buying an R4 SDHC.Please research your options before buying a flashcart to avoid poor quality/poor compatibility.
http://forum.romulation.net/index.php?topic=43005.0There are better options.

You'd better choose from Acekard 2i ,Supercard DSTwo, CycloDS(works on DS/DS Lite)

yes, order the acekard 2i, its a better card, and its 15 dollars. and use this website http://www.shoptemp.com/ its pretty good, its reliable and recommended by romU

Or if you want something a little pricier and fancier that can emulate GBA games and auto patch AP, go for the Super Card DStwo.

or the iedge is good because its cheap being updated and it to has a auto patch.
its also well built and comes from a well respected company.
