Adding a 2013 update to this thread - called fuji this morning in search of a mk ii AA holder, was told they only have only mk iii in stock ($65 + $10 s&h) and that it wouldnt work with i or ii (which i slightly ignored as i had already ready the mod tips on this thread.) Called back to pull the trigger on the mk iii holder, and was told that they had actually found an extra mk ii holder in their warehouse, which they sold me for $40 + shipping.

So, I may have gotten their last mk ii holder, but this confirms that they still carry the mk iii holders which can be modded as discussed in this thread
