It is a good idea to put your electronics devices on a UPS – it helps protect them from surges and dirty power, as well as riding out any brownouts or short black outs. I keep all of my entertainment center devices – TV, TiVos, receiver, etc – connected to UPSes. I’ve had my power go out, flicker, etc, and my TiVos keep right on recording without a hiccup – let alone damage.
I just got a notice from Buy.com that they’re offering the CyberPower 685VA 390W AVR UPS, with 8 outlets (4 UPS, 4 Surge only) as well as surge protection for RJ11/45 and coax, for $54.95 with free shipping. MSRP is $84.95, you save $30. That looks like a pretty good deal. I use similar Belkin UPSes for my gear, it is a good form factor – the widely spaced outlets allow for power adapters that many devices use.
(They have the Samsung HL-R6167W 61″ DLP TV for just $1,379.99 – but it is only 720p. I have the HL-S6187W – 1080p.)
