broken appliance with 2-3m cable (St Albans AL1, nr Marshalswick)

Hi, I'm looking to replace a damaged cable on my Black & Decker Alligator so if anyone has a long-cabled non-working appliance they are looking to trash, I would be grateful please. Garden tool, vacuum cleaner, anything that's not working. Anywhere local to AL1 would be good. please. Thank you
