What should I expect to pay for a 1gb SD card for my sd450?

[Kiva]

Hi there

Need to get an 1gb SD card for my Canon sd450. I see on that other site's ram page that they go for about $30 + tax and shipping. I'm in CA..

DMS has one for $39 by "transcend". There are a million brands and price ranges...what the heck am I supposed to get and how much should I pay for it?

thanks
