I have similar setups as there are a bunch of legacy PDUs out there (even with A and B feeds) that have ethernet and telnet and aren't supported by crappy enterprise tools anymore but still work perfectly fine. It seems like those have flooded the local remarketing companies over here at far lower prices than APC and Eaton stuff. Make sure everything is configured with auto-boot/auto-power-on and a reset is a single command awayThe alternative would be getting (often available for free to IT guys during server room changes/moves) a switched PDU, like APC AP7900B.
I won't pay any more than $50 for such a device but even used ebay prices are too crazy. With this, you could reboot remotely the modem/router separately or together without going down to the basement. Source: this is what I do
Some of the avocent models also come with per-port power logging, voltage monitoring, quality detection etc. Totally overkill for small setups but for the price of a high end extension cord it becomes a "why not" very quickly
