The gorm board does looks the quickest and easiest. The reasons I built mine the way I did were
1) I have to be able to flightcase it - everything gets chucked in the van including PA, drums, guitars so having anything loose isn't an option
2) I don't want to put velcro on the bottom of the pedals so I've cable tied everything down. This is really secure but calls for vertical rather than horizontal strips across the board (not literally vertical, but you know what I mean, running top to bottom of the pedalboard case).
Also it was really quick and easy to saw the strips into sections, the only waiting time was waiting for the glue to dry.
