I don't know much about these, but why is this:

so much more expensive than this:

And if there is a big difference, would the cheaper one be fine for protecting a projector?

The expensive one is a true sine wave.. the cheap one will be fine. I use one of the APC smart ups was about $140 and works great for my projector.. sine wave is not needed of this type of application.
Great, Thanks. I might get one of the beefier cheap ones, and run my projector and HTPC off it, and then get surge protectors for the rest of the gear.
