Godlyke or 1spot.
Both of them now have an input plug at the end, so you could plug just about any power supply (with conventional specs) in and it'll power that chain. Both these companies have some 9volt high mA output, too
They might still have some with no input on them, too. I'm not sure.
But like I hinted at, make sure you watch the mA draw of each of the pedals you're chaining. And, some pedals don't like to chain up, like a lot of digital delays for example.
