Looking for a CF card, checking 7dayshop and i read my cam works best with UDMA cards

I was getting on fine with an 8gb card but think with the extra MPs and the chances of wanting to shoot some RAW i should go for 16gb

Looking at Lexar Professional UDMA 300x CompactFlash (CF) - 16GB for £70.. bit pricey, worth it? Any cheaper places?

price is the same and changing cards in the field does risk damage, not sure on the level of risk vs running just one

Get 2x 8gb? Only reason I suggest this is on the grounds of if one card somehow dies or gets corrupted etc, you only potentially lose half the photos. Might work out cheaper too?

2 issues with that. Even if it was cheaper the CF interface on canon cameras isnt the most robust one ever produced, plenty of people would rather not have to bother changing the cards over too often. Secondly they arent likely to fail very often and by the time one does the replacement should be a lot cheaper.

Ive got a pair of 8GB ones and Im exceptionally careful when putting them in, bent pins can be costly to repair.
