I just ordered 2 Kingston 4GB 133x cards from Adorama (http://www.adorama.com/KGCF4GU.html
). They are $35 each after rebate and I have some Kingston now that have never been a bother. I got them for my (soon to be) 1D3. I will use the CF cards for RAW and SD (I got two 2GB Sandisk cards) for JEPG. The only reason I got 133x instead of 45-60x was the price. I don't expect to ever out run the buffer.
Peace be upon you
