The current draw is now listed on each individual pedal page as well as the listings in the shop. I could also put them all together on the About page if that would be helpful.

I have always powered my pedals using Visual Sound 1-spots, daisy chaining up to about 8 pedals and have never had any issues, nor can I think of any reasons that the circuits would have any problem with that. I've also never heard much feedback from people saying that they had issues with doing this. I think of the 1-spot as being a pretty average supply - it's totally adequate but obviously inexpensive and without any isolation or other features that higher-end supplies have. If the pedals work well with this, I expect them to work well across a wide range of supplies.
But, I can't say that there could never be issues with any power supply or third party effect pedal, because I haven't used/tested all the power supplies that exist nor anywhere near all the different pedals out there. Maybe some users can post their own experiences. I would certainly want to know about it if people have had any issues with certain supplies.
