UPS - uninterruptible power supply

I'm looking to purchase an UPS. I saw this one got good ratings on Newegg, but I wanted to get feedback from you guys first. What should I know before I purchase an UPS? What do you recommend I purchase?

For reference, I'll be using it with the following hardware:
- iMac 24-inch: 3.06GHz Intel Core 2 Duo w/ 4GB RAM
- external HD

Additionally (battery backup probably not needed):
- Logitech Z-5500 5.1 sound system
- a couple of laptops

Jam it back in, in the dark.

Thanks for the input. I'm buying it now. Hopefully it works as well as the reviews claim.

There's nowhere I can't reach.

I got my UPS the other day and it's hooked up and running currently. It seems to have a lot of plugs on the back and its battery ports are supporting my computer and external hard drive with no problems. So far so good.

Now I need a storm to come along and knock out the power so I can test the battery's abilities. =P

This thing is sticky, and I don't like it. I don't appreciate it.

Good idea. I tried it and my computer stayed on like nothing happened. Amazing. I kept it out for maybe 30 seconds and it emitted the warning beeps during that time, as it should. The display actually said it would support my current load for 50 min, which sounds impressive to me. Plugged it back in and all is well.

I am a dolphin, do you want me on your body?
