I've gone and ordered a Sandisk Extreme III 4Gb card, but I already have a couple of 1Gb Ultra II cards to fall back on.

I usually transfer the images to my Mac on a daily basis anyway, I just wanted the capacity in case I take a lot of pu=ictures on a given day.

But thanks for all the help and advice, I'll let you know how I get on with the new Camera over the next few weeks.

Thats helpful. I bought mt *istD with a 256k Ultra II card which actually cost more that an 8Gb card would now, so memory is relatively cheap!

I am still not clear if its useful having the faster transfer speeds given that a 'standard' 2Gb card now costs about £20.

Thanks for the advice.

Sorry if this has been posted before, but does the SDHC compatible K10 have the technology to take advantage of the Class 6 data transfer speeds of SDHC or is it not necessary to buy anything more than Class 4? This would equated to the Sandisk Ultra II (which I currently use) but I will be buying an HC card for the greater capacity and would but the Extreme III if the K10 could use the speed.

Unfortunately I cannot get this info from the manual.
