I'm using 3 x Caline CP-05 for semi-isolated power and 2 x Donner ISO8Plus for fully isolated. Why so many ? I have three boards, in theory ... In practice there's only one or two ready for operation at any one time EDIT It's worth mentioning that many pedals will work happily with semi-isolated power supplies i.e. Separate smoothing and/or separate regulation but common Ground. A lot of digital pedals aren't so forgiving OR they themselves send interference back up the power lines and upset other pedals. THAT's when fully isolated becomes neccesary.
