UPDATE: Went quick. Already sold.
For anyone looking for a CFFA3000, just a heads up on one that just went up on eBay. I'm not the seller but just thought I'd spread the word as it's currently out of stock from Rich Dreher @ R&D Automation and he may or may not be producing them in the future (http://dreher.net/?s=projects/CFforAppleII&c=projects/CFforAppleII/main.php).

Thanks for posting that! I’ve been on the lookout for one for weeks...
Here's another:

Without WOZ / WOZ2 diskette image format support I anticipate the price would drop down further. I don't mind getting one damaged and cheap though some day.
That is a good point and why I also recently picked up a Floppy Emu in addition to the CFFA3000.
