APC SmartUPS, Cyberpower PFC Sinewave or Smart App, > Eaton 5P/PX or 9 series, Tripp Lite SmartOnline, etc. I absolutely agree. I have a large line conditioner I pulled from a mini- frame that was being decommissioned and scrapped. It filters line noise, spikes, transients, high-freq noise, etc, and contains a constant voltage transformer that can even buck up short line voltage sags. There is no such advantage to having/using such a beast only to place a non pure-sine wave UPS between it and the computers. Defeats the purpose of having it in the first place as such units will only reintroduce all the crap the line conditioner cleans up. Of course, the obvious idea would be to put the UPS in front of the line conditioner, but that's also a no-go for various other reasons. Was just bringing this up to say: spend the extra money and get something good. My main background early in life was analog electronics and RF, before I got into computers. I've been looking around for something inexpensive for home use, but my show-stopper spec is I won't use anything that isn't pure sine wave. And that translates to $$$. Haven't found anything yet that is inexpensive and satisfies my requirements. -Mike
