B&H Photo has the first generation (?) Delkin Black 325 GB CFE-B on sale for one penny short of $200 through this evening. For me, this brand and this capacity are my preferred cards for both my Z9 and Z8. I know that it's not as potentially fast as the new generation of cards, but it has always met my needs.
