Yeah the CF compatibility list on Tarkan's site is not 100% accurate. The Komputorbay 128GB 600x works just fine with the Tarkan adapter. The Dolgix 133x 64gb or 128GB card also works fine. Those two brands are probably the least expensive ones you could get. This 128GB CF card should work as well, but personally I have not tried it yet. Remember seeing a pic from a head-fi'er of CF mod with this card and the Tarkan.
