T-Rex Fuel Tank Classic

I use this to power up my small collection of pedals, got this because then I've got outputs to spare.
Despite the outputs on this not being isolated, it sounds totally fine. I do get very little hiss, however, it is barely noticeable, and I believe it is there regardless of whether I'm using the power supply or not.
The only con about this is that you have to manually put in the power cable either into the socket or into the device to power it on, i.e. there is no power switch. Perhaps it is for the better, so you can't accidentally trip it, but sometimes I wish there was one.
Just in case you haven't already, check the compatibility of this with the pedals that you own/intend to purchase - it only provides 9V and 12V. I, for one, have a 12V pedal that requires 560mA of current, and this power supply can only give 500mA, thus the pedal doesn't work as expected. If you happen to have one, perhaps the Fuel Tank Chameleon is the best choice - because the outputs are isolated, you can buy a voltage/current doubler cable to meet your pedals' requirements. However, it does have less outputs.
