Ultra III?
If you are refering to SanDisk I would say that the level following
Ultra II is Extreme III

Correct.
I use both 4gig Ultra II and 8gig Extreme III.
My observation is that the Extreme allows me to shoot a few more
action shots of the dogs in a row before the buffer can't get the data
to the card fast enough anymore. Testing just now, I'd say 17-19 RAW
shots without pause as opposed to 13 or 14 with a K20 set to "Hi"
continious, 250th sec, manual focus. With the Ultra 2, it's about 3
seconds before I can shoot another shot. With the Extreme 3 it's less
than 1 sec. In either case I can only get off another 3 or 4 shots
before it's bound up again.
If I take 14 shots with the Ultra 2, it takes 17 seconds for the
camera to dump them all to card.
If I take 16 shots with the Extreme 3, it takes 12 seconds for the
camera to dump all to the card.
The image in all cases was the same, a wooden door with grain and a
Naval cap hanging on it with scrambled eggs on the brim and lettering
on the front.
But in San Disk land, there's a big price difference. I usually pay a
bit less, but the last 8gig I got from B&H on a gift card and paid $57
for it. These are all SDHC, BTW.
Hope this helps.

I just purchased the K20D and was wondering what memory I should go
with,
SDHC Ultra II or Ultra III.
I have a mixture of both. Either works fine, the Ultra III is twice
as fast at read/writes, I believe.
The K20 buffer is large enough that unless you are a tail gunner,
you probably won't fill the buffer no matter which card you use.
