I would also like to ask about SD-audio. Since I cant create mp3`s with kn2600 alone, do I need to buy that (?150) technics software-package with sd- reader/writer? I think there might be easyer (cheaper) solutions too? Please let me know how you`ve done it!

That would mean sd-unit (reader/writer) plus ________ ?
