I use a Cyberpower UPS, made for computers and purchased 6 years ago for under $100. I had to replace the lead acid battery once 2 years ago for $35. I use it mainly to protect the DSP-based pre-pro from voltage dips caused by my amps turning on. The voltage dips were causing the pre-pro (Sherwood-Newcastle P-965) to malfunction. Problem solved with UPS.
Chad, I'm surprised you are able to use your battery backup with your amps. Most battery backups I have seen have wattage/current limits well below that demanded by a decent-sized amplifier.
