Why not?
Actually, just wanted to point out a rather amazing price on RIDATA 52X TWO GB CF cards at MyDigitsalDiscount.
Only $300.00.. exactly twice the cost of a single ONE GB card... which is a price breakthrough. This is the first time I have ever seen a 2GB CF sell for this low,. and the RIDATA is a proven performer in the MkII. And it has a lifetime warranty.
Now.. as for MDD.. I have a hard time recommending them due to the total lack of ability to communicate with them after a purchase. Lets just say.. you Get a good price,. if it's in stock you get it,.. but if the card dies? How do you get an RMA? Your probably going to be left dealing with the manufacturer.
Oh.. what on Earth was "5 Gigabytes In the MkII" about you ask?
I also got a RIDATA 52X 1GB SD card at a respectable price... add that to a 4GB Microdrive and I can pack 5GB at once into the MkII 
I suspect I'll use the RIDATA 2GB CF card more often now though.
