Has anybody got one?  They are really expensive! Does anyone know are they worth the money?  At the moment I use SanDisk Extreme III 4GB cards.  Reading through the specification on my new camera (EOS 50D) it says with UDMA cards I will get better performance.  Is this true or are Canon wanting me to go out and spend more money?

The Sandisk Extreme III 30mb/sec version is already a UDMA card....older version Extreme III's are not.

In youth, we learn....with age, we understand.

Thank you Gradient, I do have the 30mb/sec versions so no need to fork out more cash.

I have a couple but my cam is not able to use the advantage.  These cards do seem to download to the computer faster and with few problems through the card reader..     The difference is not worth it for me since the entire set up is not set for the action of these cards.

 I bought two 8gb 300x speed umda lexar compact flash card to use with my 5D mk2. Its 100% fantastic, but only when you use it with a umda card reader.
With the umda card reader, coping 8gb worth of 5d2 video files to my imac last just 5 or 6 minutes.
With an ordinary 2.0 usb card reader, it takes up to 47 to 50 minutes to copy onto my imac.

Its expensive, but definitely money well spent.
