I'm sorry if this isn't the appropriate group for this kind of query,
but I just didn't know what group to use instead.  If there's a better
group available, please tell me so I can direct myself there ...

I'm looking for a UPS for my A/V equipment.  I saw one for sale in
Crutchfield's for $350.  It's a unit that does 20 minutes at 450W.  That's
more than enough for my uses, as I'm purchasing it primarily to keep all my
equipment from forgetting the stuff I store in it, not actually run the
equipment.

However, I understand that there is more than one kind of UPS technology,
and that some types fail when they actually need to be used.  What are
the different types of UPSes?  As an aside, how can I find other
manufacturers of small(ish) UPSes that cost less?

Any help in this matter would be greatly appreciated.  (I don't want to
spend that kind of money for the use I have, but I lose power so frequently
that it's driving me bananas having to reset all of my equipment.)

Oh -- and if the UPS can only handle a 450W throughput, does that mean that
I can't pull more than 450W through the box at any given time, or that's
just all it'll support if it doesn't have any juice being sent to it?

Thanks again.
