I use UPS's on all my computer equipment and for that matter my (what I consider) expensive HDTV's and related equipment too.
APC offers a large one (i.e. it keeps running longer during power failures) and you can get replacement batteries should you need one-but usually the original batteries last 3-5 years.
Check out model# BR1500LCD. They cost under $200 and have like 6 plugs on the back for every piece of equipment in a room since you can also run extensions to them (this is probably not recommended, but I do it with small draw accessories like my DSL modem, etc.) Of course it also stops surges.
By the way a Genius bar guy told me that all surge equipment should be replaced after 6-7 years since they loose their effectiveness after that long.
