Star Wars Lightsaber Forge Darth Vader Electronic Extendable Red Lightsaber

For all the little Jedi's in your life (and the big kids like me too!). This is a decent model that normally hovers around the 20 quid mark. The other models aren't as low in price at the moment but I'm still watching them.

EDIT: for some reason you've to go over to the New and Used section to get a new one from Amazon.
