I've used Olson in the past; these days I generally use "Data-centre" grade stuff - old 19-inch-rack power-strips - Dell P/N G744N (32A input, 20 outlets) are available at pretty-much scrap-prices since these days a data-centre needs each outlet in every rack to be individually IP-addressable and able to report on power-consumption so the old non-individually-addressable stuff is being thrown out.
