I've sort of asked this before.  I need an SD > PC Card adapter for a Kanga.  It can be Cardbus or PCMCIA; I'd just prefer it works safely.  I'm open to other storage standards I just happen to have a more than adequate SD card so I figure that's a logical starting point.  I've also considered a CF > PC Card and then SD > CF adapter.  Not my first choice, but I haven't found a good direct option so far.
