What guitar cable should I buy?

I am new to playing electric guitar (but not to playing instruments) and my guitar has a bit of backgrou buzz. I have tested it and know it is the lead that it was supplied with, so I need to purchase a new one. I wish to get one from this site : http://www.gak.co.uk/en/instrument-cables and it will be used to connect my Les Paul Junior to my Epiphone 10 Watt practise amp. Which cable shouldI buy from the list and how much should I spend? Cheers, Jules
