For anything other than very basic cheap battery-backup, there's really only APC. A decent UPS can help your hardware by 'cleaning' the power - maintaining a constant voltage and removing spikes. Our office regularly drops as low as 204v (we are in the UK and should be running 230-240v).
One thing I would say though as you are a musician - there's a heavy amount of interferance from some UPS devices so be careful on placement. My home connecton went up from 800kbits to 1400kbits just from moving the APC Smart-UPS1400 that protects the firewall / router away from the phone line.
