CyberPower Intelligent LCD Series GreenPower UPS CP1500AVRLCD 1500VA 900W 8 Outlets UPS for $149.99 + free shipping
Great price on this beefy UPS. Included software is a little lacking in usability and features compared to the Belkin Bulldog software I had with my past battery backup, but the status display right on the front of the UPS makes up for it. I'm running 3 of these (2 of which supported the servers of a recent convention of 30k+ attendees) with no issues. I've had these on a Newegg watch list and $149.99 is as low as I've seen them go.
