not anymore, not with HC. just get a transcend or a-data class 6, you can find them quite reasonably priced on ebay i think. watch out for fakes though. and afaik sandisk should still be avoided
No offense, but that's not true. My 4 GB Class 4 Kingston Japan had lockups in Castlevania POR(by comparison, my 2 GB Kingston Japan had no lockup isses with the game). It also gave me several issues with AKAIO. I just got the Trascend 8 GB class 6 card and I'm not having these problems.
Kingston only rebrands Toshiba(and possibly other maker) cards. They don't offer any class 6 cards.
My own experience with SanDisk is to avoid their 'consumer grade' products, which are the blue colored cards. I've have numerous ones die unceremoniously while in my digital camera, where such data loss is not merely 'annoying'. Their professional grade products are rock solid though.
