Rich Dreher has sold out his 3rd run of the popular CFFA compact flash/IDE card for Apple IIs. He is taking names for an upcoming 4th run.
He also continues work on v1.4 of the logic chip found in current CFFA cards, which will be user-replaceable. He hoped this update would allow larger size compact flash cards to work with the CFFA, but it turns out that existing cards will need a hardware modification. More info is on his website.
