Power Back up

[flipsyde2000]

As I near the completion of a home theatre that took nearly 4 yrs to put together and the only thing I desire from here on out is new media and a 2.0 blu-ray player, I ask myself should I get some sort of Battery Back up device to insure safety for my equipment for power outages.

With this question I have the following quesst for knowledge.

A) What is the best back up unit out there?
B) Do I really need it?
C) I have a power conditioner already is there a unit I could use in conjunction?
D) Do I try and find one that will allow my family to have something to do during an outage?
E) Can I find one that suits my needs for less than $300 or so?
F) What is a good reliable brand?

Any help is much appreciated in this matter
