An un-interruptable power supply (UPS) is cheap insurance against lost work.
A UPS of suitable size can be obtained for about $100 from almost any office supply store. In addition to protection from power failures, surges, brownouts and spikes, many models also feature line filtering, which can help remove unwanted noise generated by electric motors and light dimmers.
A 250 VA model is more than adequate to power the 880, and one or two external drives or backup devices.
