Even the 1500VA units are a lot less expensive then they were 5-10 years ago. $250-$300 to protect $2000-$6000 worth of hardware is worth it in my book. (I prefer the Smart-UPS units for a variety of reasons. Line filtering, voltage regulation, and nice reporting features via apcupsd. We have MRTG polling the apcupsd data regularly and have graphs of line voltage / operating temperature. There are even variants with the audible alarm disabled, which is perfect for a home office where you don't need that high powered screech.)
