Tripp Lite has been around for ~80 years doing power related devices. They have been making UPSes for around twenty-some years. My first power bar happened to be a Tripp Lite, and it was built like a tank, metal case, RFI/EMC filtering built-in, resettable circuit breaker. I've also owned a couple of Tripp Lite UPSes, and used them professional as well. I've always been satisfied with them.
They don't target the consumer market, as far as I know their core business is more industrial then APC, which is not a premium UPS manufacturer in my experience. Professionally, I've seen nearly twenty APC UPSes that the controller electronics or transformers die, as opposed to battery failures. The environments were harsh, with large diesel generators used for backup power source when commercial power failed, and some environments were high ambient temperature work areas (Middle East), but UPS failures shouldn't be frequent if you don't abuse (overload, not ground) them.
Brands like Leibert, or Powerware (now Eaton), or Tripp Lite are brands I prefer for over 1 kVA UPSes.
