Go to the Simpletech.com Estore, add the Simpletech ProX 256MB SD card to your shopping cart ($86), add coupon 24834-876 (-$32), S/H is free, makes it $54 shipped, no mail-in rebates.
I received mine about 5 weeks ago. This seems to be an ongoing promotion that was down for a while but is up again.
This is probably the highest quality (and fastest) SD card you could get right now, the exact opposite of those crappy Sandisks.
Now if only someone could find a good deal on the 512MB model...
