But for most practical purposes the Cisco supply is a good one. Being only slightly nuts myself. I use the Cisco supply but I built a small power adaptor board with matching connectors and some "pi" filters made with RF choke and capacitors. I realy don't thing the filters are needed but I wanted a connectorized installation and a small choke was as easy to solder in as a length of wire.
