Hi Magsafe!
I had a look on Amazon, and this one looks good:
http://www.amazon.co.uk/Canon-Lide-C...&s=electronics
I like Canon's, they are a good marque so I wouldn't be worried about quality or anything.
Aside from that, just take a look on eBay (don't know whether you use it or not) and just keep to the good brands - Canon, Epson, Brother etc.
