Loads of options these days. On my various boards I've got the True Tone C6 (thinline - gets under a Nanoboard), a Voodoo Labs PP2, and on the massive board a Gigrig Power Generator modular set up.
Power supplies are never exciting, but don't begrudge them. Nice quiet stable power is great. And considering the cost of 9V batteries they pay for themselves pretty quick.
A lot of the cheaper / smaller isolated ones don't have 8 outputs though. But you can still daisy chain a couple of outputs for pedals that won't be a problem leaving the difficult ones on their own output.
Also be aware that some of the posh reverb and trem pedals have high current draws that some power units can't supply. So if you are aiming for an Eventide or Strymon then you'll need to check the current draw specs.
