My board is expanding, like my waist, and I have outgrown the little powered board I bought when I foolishly thought I could control my pedal acquisitions. So, I need one, possibly two power supplies. I have narrowed it down to two potential units, the Voodoo Labs ISO-5 and the T-Rex Fuel Tank JR (I am likely to place one on each "half" of the board). Pros and cons of each? I don't want a large unit because I only need 9 or 18 volts, no 12, so I don't want to lose outputs that are dedicated to a voltage I won't use.
