Schneider APC Back - UPS Surge Protector - Black (BN450M) - Target $20 YMMV
Target has APC Backup up on clearance for $20. Regularly $40. This is a clearance item so it's YMMV. There was 6 at the target I was at. I picked up 3 of them. It looks like there is plenty of inventory in Denver.
The BN450M has six surge protected outlets, four of which provide UPS battery backup, and a 255-watt/450-volt ampere output power capacity.
