I've been using XD cards since they came out (love my Olympus) and just got another camera that uses them.

I get all my cards at e-cost (www.ecost.com). If you are paitend and keep checking, you can get 128's (olympus cards with the panaroma feature) branded under other names for as low as $30 (three weeks ago they were $34). They currently have the 128's for as low as $42, but I usually buy only at $35 or less for the 128's. Keep checking every few days, they come up in their Bargain Countdown area frequently.

You can also get them on Ebay for about the same price, I've never gotten one there, but do see the 128's for $35 or so and the 256's for $70 to 80 all the time.

They are extreamly expensive over the counter, get them mail order.

They are very small, and quite durable, I've been told they can survive a trip through a washer and dryer, not that I would every leave two in a shirt pocket and wash them or anything
