I've been running a pair of these for almost 3yrs now: http://www.memoryexpress.com/Products/MX26907
originally the plan was to use one for my 'front of the room electronics' including the tv, receiver, and game consoles, and one of the 'back of the room electronics', projector, HTPC...
they have been awesome, and have definitely saved me from losing my spot in a game, or work I hadn't saved on the pc. BUT, the 1000VA was not enough for the 64" f8500. when I first got the tv, I thought it had the dreaded 'buzz' because when a bright scene came on I heard this super annoying high pitched electrical buzz. I tried messing with settings and eventually realized it was the UPS behind the tv making the noise. when the tv is drawing max current, it's too much for the UPS to handle. now it might be JUST enough if the tv was the only thing plugged in, I'm not sure, but it's definitely not what I would consider a comfortable fit. my plan now is to get a 1500VA version for the front, give the projector its own dedicated ups, and the htpc which has grown since will get its own UPS. a bit overkill, but I don't really have any better place for the extra 1000VA ups, so why not.
anyway, I would recommend going with something larger, at LEAST 1000VA if the tv will be the only thing on the battery protected side. but moving up to 1500VA is smart imo. then you can plug in a couple other sources if needed, and be fully protected. I had my game console lose power one time while saving years ago, and it erased ALL the save data I had. it was a bit of a major blow actually. many of the games I had save data for I haven't played since. stuff like guitar hero where you have unlocked all the songs suddenly just becomes frustrating to start over
