Hi Willem,
I have a cheap little card reader called Travel Flash that I bought through Ebay
(for under $30 AUD plus Postage). It reads SD & Multi Media Cards.

It works okay with Thomas's program and it works with the software that comes with the kn7.

Mine definitely DOESN'T work with the Panasonic SD Juke Box software.

The box also says it works up to 128mb capacity. I just formatted my brand new 256mb card and it seemed to work okay, but I can't be sure till I do some saving etc.

best wishes
Rikki
