The apc7900 is reasonable at about $420us for 8 ports; has a serial and
ethernet ports, and a reasonable (scriptable) CLI avilable via the
serial line or telnet (ssh too, I think) and a digital current readout.
I like 'em.

For home use, if you have the time to make it work, search for X10.  Way

For modern, server class PCs, try ipmi.
