My sister, who is on UFB, just upgraded to the 200/20 VoIP plan with Spark. This is done through Downer, and they suggest in their sign-up literature that she gets a UPS, which is something she'd been thinking of doing for a while anyway. She was wondering what make/model would be best for reliability, cost-effectiveness and ease of use. It would just be to keep the Internet and phone going in an outage. Suggestions much appreciated.
