Where do you get cheap 9v wall warts? I'm about to add my third pedal, still not enough to justify something like this, especially since I don't plan to add more, maybe just swap some out. So, one more wall wart for now.
Couple options including cheaper multi-supply and a universal 9v adapter:

Don't know what pedals you're using, but one of those might work for ya. Otherwise, maybe head to Radio Shack.
