43 Folders: Custom index cards from your own printer: "I have been using a Canon iP3000 to print onto store-bought 3x5 cards--it works wonderfully and it's a great printer. It prints natively onto 4x6 cards, and it's really easy to print onto a 3x5.
I've found that iCal is great for a HPDA. Save the week view as a pdf, and open it in preview. Select the area you want, and print the week onto a 3x5 card. It works wonderfully."
