Recommend a good UPS please

Anybody know of a floor-standing device with enough juice to run the setup in my sig for a few minutes whilst I power it all-down when the power (frequently in summer thanks to the neighbor's AC load) cuts out? One with as few blinking lights as possible would be a bonus. And black. I'd run it from the wall outlet and then to the power conditioner; any problems with running a conditioner off a battery?

Thanks
