Wow - they're already up to the 7th version!
I've used a few of the Digital Loggers units - versions 3 and 4 less than 2 years ago and they've served their purpose very well, more than paying for themselves in saved gas.
In a commercial setting, i've used APC and Tripp-Lite's Switched PDU's (which are basically the same thing except made to go in racks and generally use the kinds of plugs you see in a data center, like 20A twist locks) on nearly every piece of equipment I manage - or at least I did before moving to data centers that never lose power, and virtualization that lets you sequence machine startups. They're also an absolute lifesaver.
there's another option too, with Ubiquiti's mFi line - it's not very mature yet, but they have a more complete ecosystem where power strips can switch on/off based on other events and you can have a single large spread out system where some lights are controlled by time, others by automation scripts; others by motion or temperature, etc - so it's quite powerful when you build it out.
But back to just normal power cycling needs - if you don't need something like a true switched/metered PDU like APC, then those digitalloggers ones are pretty good - and they have a few options, like 24 or -48V telco versions, vertical, rack mount, etc - they're not overly fancy but they serve their purpose and the price is right.
