I'll echo the APC recommendations.  I have 3 of the SMART-UPS family (the
older serial-only models).  I use NUT (pkgsrc/sysutils/ups-nut) with them
but there is also apcupsd.  They do:

  notify when switching to battery/mains
  shutdown after configurable delay
  startup after configurable % charge

The APC UPS' are also common 2nd hand (and refurbished with new batteries)
and it's possible to get the batteries more cheaply than the APC price.

IIRC, the SMART-UPS is available in at least 700, 1000 and 1400VA versions
both standalone and rack-mount versions.
