I've been using the Furman sequencer in a recording studio application for a few years and it's been reliable. Using 3 stage powerup/down wired to a key switch. (Literally, a key is inserted and turned like an ignition switch to actuate turn on and off sequences. Eliminated the nasty pops.
Use that in conjuction with:

Plus one of their ups units for the computer.
I think their stuff is good.
