hmm, you can't compare to "Raritan" generically because the raritan have vastly different product lines too.
if it works and does what you want, great... base it on your needs
I have a few WebPowerSwitch.com units I was messing around with for my home, they're not beast-datacenter products but they work... I haven't used them in years, but their site redirects and they look in business!! This could be another option but more $ than the used ebay prices on the enterprise gear.
