Everything you need is there... We look forward to seeing you.

I use Compact Flash in my PCMCIA adapter. I have a few different cards (read my article there as to why this is good) and usually have a 512MB card in for general purpose. You can't put audio files in it, so this is sufficient for even the largest of style and SMF collections, IMO...

Just remember to format it with the E60 (less problems, and gets rid of any junk on the card like trialware, etc.)
