When I attempt to follow those links to Amazon UK, they give me a page-not-found error.
The two brands that probably have the highest reputation are Lexar and SanDisk.
Cards can fail and do wear out after enough "writes" to the card. I always suggest that rather than getting one large card, get two smaller cards. There are two reasons... first and foremost is that if the card fails it's nice to have another card handy. And second... when I unload cards, I put the card in the computer to copy the images off the card (it's faster than using the USB cable). At some point, you may be miles from home and get the dreaded "no card" error -- only to realize that it's because the card is still in your computer back at the home or office.
