Whether you are looking for a brand-new or second-hand mains transformer, eBay offers one of the largest selections available online. With 48 active listings at the time of this page's last update, you have plenty of choice across different conditions, sellers and price points. The cheapest option currently starts at £3.02, while premium listings can reach £139 — giving you a wide budget spread to work with.
