Here's what we just started using:
APC Smart-UPS 1000 XL - $500
APC XL Ultra Battery Pack 24V - UXBP24 - $500
APC Management Card - $200

The downside to this is that it isn't a rackmount solution.  The external
battery pack is BIG as it houses four "car" battery-sized batteries.  These
are chainable too which is nice.

Based on a 300W load, here is the uptime you'll see with the battery packs:

SUA1000XL + (1)UXBP2411 hrs 57 minsSUA1000XL + (2)UXBP2424 hrs 31 minsSUA1000XL
+ (3)UXBP2435 hrs 43 minsSUA1000XL + (4)UXBP2446 hrs 55 mins

So, for $1,200 you'll get a UPS w/monitoring and nearly 12 hours of uptime.
 Drop in
another UXBP24 for every additional 12 hours of uptime you need.
