Right angled daisy chain (more £ but saves space): [url="http://www.ekmpowershop8.com/ekmps/shops/madisaf/madison--fifth-daisy-chain-39-p.asp"]http://www.ekmpowershop8.com/ekmps/shops/m...-chain-39-p.asp[/url]
The DHA will run at 9v but will sound better at 12v.

That Johnnyshreadfreak supply gives 1500mA which doesn't leave room for too many other pedals once you've put the DHA on there. Most ODs/fuzzes etc don't use much current, it's the digital ones that can eat over 200mA and of course tube pedals. The Diago unit supplies 3000mA but is more expensive, then there's the Voodoo Lab Pedal Power which is megabucks!
