I dont know what model you are talking about that didnt have Power Conditioning, but I couldnt find a line that didnt. Quite possible it had an additional unit to increase the conditioning for ultra sensitive equipment or increased filtering from line noise. Not sure, but it has been some time since they sold models that didnt have Power Conditioning. Personally I have had some cyberpower UPS systems that had premature battery failures within months of purchase and entire units that failed soon. I only buy them when I want ultra low cost (usually for clients that dont want to have one at all but I insist they use something). That APC linked by the OP is about right for that model. APC sells that unit for 99.99 off their website so a couple bucks off and shipped is pretty good. Should do you fine either brand you get as long as you get something. Just didnt want you to rule out an APC unit just because. APC makes fine UPS units and I have always had very good luck with them and have deployed hundreds in the Hospital Network I help administrate here. Good luck...
I wish you were right but most low end APC UPS's do NOT have AVR and some of the ones that do only have AVR Boost (no Trim). The Back-UPS ES, CS, and a few others do not have any AVR. The Back-UPS RS series does (though the RS 800/900 only has Boost). The OLD Back-UPS Pro's and most of the Smart-UPS's do have full AVR.
As for other brands, almost none of them have full AVR (just Boost). All the ones I looked at that claimed AVR only had Boost (Belkin, Cyberpower, Tripp Lite, etc.). It seems that there are very few UPS's with full AVR for under $200.
To the OP, the ES series is decent though low end. BTW $93 is not a very good price for that model.
