Missy. You want a type I compact flashcard. Sandisk and Kingston are recommended brands. If you go to www.thenerds.net they have a Sandisk 4 Gig compact type I flashcard and the last time I checked the price was $143.00. Go to their search engine which you'll find while working your way down the page, and type in the model number, SDCFB4096A10. You can order online or by phone: 888-566-6373. This is the best price I've seen. Other websites to check are as follows: www.pricegrabber.com www.pricescan.com www.mwave.com www.onsale.com and www.PCmall.com Have fun.
