Birthday present ideas for a teenage boy?

[Snowyj]

Help...I really struggle to think of presents for teenage boys. Budget £15-£20. He prefers presents to vouchers/money. Any ideas...

Could you get a box set for a programme he likes to watch? play.com are having a sale at the moment

Or maybe a funky t-shirt? The above link also has a clothing section.

Great, thanks Tidy

Hmv has loads of gifty things good for teen boys or you could try graphic novels from water stones, sports stuff from sports direct or anything from Superdry/Abercrombie/hollister.

Thanks Ingles...bit worried about my budget (lack of) for Superdry/Hollister/Abercrombie. I went to Sports Direct but wasn't inspired.
Struggling too much, sort of defeats the object of present giving; money isn't an object in his house, which doesn't help.

lots of gadgets under £20 here
