Where can i get a 6 way boxed power supply???

im constructing my first pedal board. I want to power 6 pedals, and obviously need a power supply. I want to spend about £30-£40 AT MOST on a power box (and needless to say i need at least 6 outputs). i've found one for £20 but it only powers 5. Does anyone know of any power supplies that have enough outputs for my needs BUT are also within my price range?? thanks
