Not so much an accessory specifically for the NIT but with it you can have your cake and eat it too, sort of.

I bought one of these and can confirm that this adapter does work with SDHC cards. I'm using this adapter to plug an 8GB SDHC card (transcend class 6) in my Nikon D300.

So with this adapter and sticking to SDHC cards, you can just stick with SD cards and not bother with CF cards and then you get "one card to rule them all". Unless you're a sony fan, then I feel for you.

Edit: I guess I should note that even though I have the same camera as the guy who made that review on amazon, we are not one and the same.

Now if only there was a SDHC to CF1 adapter.. looked but just doesn't exist.

I know its possible.. cause Minolta or was it Nikon.. distribute their own branded SD to CF1 adapter.. but it doesn't support SDHC and its no longer available.
