One spot works fine for me. I play out occasionally, and I have not had any problems. For some pedals, you must remember they require an independent power supply to not create noise. I am talking about pedals like loopers, some multi effects units, etc. But the One spot works great for most normal stompboxes. I have the initial unit, which has five spots, and a five spot extender, so after you account for taking up one spot with the extender, you can power 9 pedals with one device. I think you can get both the unit and the extender together for between $20 to 30 shipped online.

I am not saying it is the best or whatever, but it works for me just fine and is economical.
