we recommend nds-card.com, as it is the gbatemp official sponsor. buying from them supports the temp, in a round-about way.
it will work fine with non-sdhc msd cards. they just toss that on there because there was a time that sdhc was a feature. with that said, why not pick up a transcend or adata msd card to go with your new flash kit? these two brands are the most recommended for flash kits. i have a bunch of 8gb class6 transcends that i have abused during years of beta testing, they still work amazingly well and give me no trouble.
